I also thought Paladins were Lawful Good (like Superman). I like that they have a bit more leeway.

I think you should probably "punish" anyone who does stray too far from their alignment. Maybe without them even knowing. Like an item/ability that used to work, but now doesn't (I'm pretty sure there are items sensitive to alignment?) or NPCs reacting differently. (But read on as I don't think it should be black and white.)

"As I spent more time in the world, I realized that taking the middle road wasn't going to work. I had to make a decision. Rise to good and be good. Or take the way of Evil because good is dumb. And because sometimes, the only way to defeat evil, is with greater evil." So right now, I'm neutral because I'm young and naive to the world.
 
So here's the thing: We don't walk around in life with "Neutral Good" or "Lawful Evil" tattooed on our foreheads. If Alex starts dabbling in necromancy, NPCs won't know unless they witness it or we tell them. Animals will know because of their ability to sense evil/intent, but people won't. (except maybe Paladins?)
I love the idea of your wizard wanting the power of necromancy, but does learning it make you evil? I understand it would to someone who sees you use it or it might make animals nervous around you, but would those of us in the party understand and be able to deal with it? BeeDee, in particular, might have a MAJOR issue with it. Hell, his natural abilities are geared to fight the undead. How about my Chaotic Good rogue? My "I don't give a fuck" nature says yes, but would the good in me hate his use of it?
Wouldn't the party dissolve, potentially in the middle of the quest, if Alex starts turning evil?

I think we erred out of the gate. Our characters needed to meet and talk about our backstories. Notice I don't say look at each other's character sheets. I think there should be two backstories, and both are 100% true:
-Your history, skills, and motivations you tell the party. We can do it here since we forgot to on day 1. Everyone just needs to write up something that fits their character and their abilities. So to let you know Koban has a high investigative skill I would say something like, "Koban is drawn to mysteries like flies to shit." 
-The second "backstory" are private motivations that should only be between you and the DM. This includes things that will help him craft the story and ensure you behave correctly. Your alignment, a species that really pisses you off, things your character loves or hates, overall goals for your character (to get rich, to become a god, etc.), etc.
If you have trouble there, here's 
a link to help I posted earlier about personality traits, ideals, bonds,
 and flaws. I added one of each to my character sheet before the last session. 
Here's a great list of other fictional characters and their alignments to help you there.
USING ALEX AS AN EXAMPLE:
To the party:
I was born in Tamaria (Is that a D&D place?), but never knew my parents. I was taken in by a less than successful inventor and raised to be open minded about the workings of the world. He taught me to question why things are done a certain way, and to search for better ways. "The impossible doesn't exist until you tell yourself it does" is something he always told me. I always had a natural curiosity and talent for magic, and I'm always looking for way to improve. I want to not only improve my own skills, but possibly the magic itself. Material goods mean little to me except as a means to achieving my goals of knowledge. I want to leave a positive mark on the world and inspire others. 
To the DM:
Alex the Artist is a fledgling wizard with an inquisitive mind. He doesn't have evil in his heart, but sees the merit in some of the dark magics. He knows he doesn't want to embrace the darkness, but would love to use a spell or two. He generally keeps this a secret from others because he knows how people generally look upon dark magic. If he began going too far he would probably lie to himself thinking he could control it. Alex is arrogant in his thinking about magic. He truly believes he can do what others have tried to do and failed. He desires to be looked upon as the greatest wizard to have ever lived. He has no desire to hurt anyone while achieving this goal, but if that happens, he feels like he can live with it. 
I'm guessing the backstory stuff is why the Roll20 site doesn't allow us to see one another's sheets? If I was playing a thief and you had access to my sheet, you'd be real world tipped off if my gold count was significantly higher or if my character background had something like "kills one party member after a quest".
What we also shouldn't be discussing in character is, "I'm a +6 on investigation rolls", "BeeDee glares at Zelda wondering if her lady parts are bleeding and the animals are smelling it", or "my alignment is neutral". In those cases, we're breaking the story and playing numbers. Shouldn't those things be: "Let me, I'm good at figuring things out", "BeeDee says to Zelda, 'Are you bleeding? I just want to know if hostile animals will know we're coming.", and "I don't care what you do."?
I mean, am I correct in this? I get that we'll have to break character, possibly a lot, to ask questions and whatnot, but we have to maintain characters AND ensure they don't know what we know. So if Gordon knows I kill a party member after each quest I go on, he can't have BeeDee take steps to prevent that. 
FYI: That will NOT be a thing my character does. He's Chaotic Good. 
I assume that we plan to stick together as a party, and thus, share the wealth going forward giving the proper items to the proper classes/person. So hopefully no evil wizards will turn on us and try to kill us all. 
And btw Troy, can I start rolling Investigative instead of Perception when we walk into an area? I get 0 Perception bonus, but I'm a +5 on Investigative. Are they really that different? Koban's class, skills, and alignment all point to him being into mysteries and whatnot, but he can't walk into a room and see anything? Is he Mr. Magoo?
