Not letting a player make a chaotic evil character in an otherwise good party

>not letting a player make a chaotic evil character in an otherwise good party

Why do you hate fun?

Try some higher quality bait.

>Not letting the players play anything even pure non-humans
>Not letting them play samael and yuhudah agents
>Not laughing your ass while the retard saint and various Christians don't get they've working with fucking non-humans for a long ass time.

Bait aside, I have a growing collection of CE concepts I desperately want to play. My DM hates CE and always tells me to go NE instead, but it's not the same.

I hate fun in the same fashion I hate freedom. I believe that the truth is important for a functional society, but that the truth tends to reduce the freedom of the liar. A man accused of a crime who is convicted using proper evidence inarguably becomes less free through fines, incarceration, or death. But society as a whole benefits as the prevention and prosecution of crime allows greater freedom in the populace at large. Thus, the truth does not set you free, but it does result in a net gain of freedom.
In the same fashion, I believe in preventing players from antagonistic and antisocial behavior towards other players unless the players have all agreed that such behavior is accepted in the current campaign's social contract. Thus, the fun may be reduced for one individual, but there is a net gain of fun amongst the group.

>not basing "fun" on the amount of fun the group is having as a whole rather than the amount one specific player is having
Bait aside I allow players to play whatever alignment they want because they aren't children and they can control themselves.
I also let them roll for stats without me seeing.

>alignments

the only CE (or alignment one) I want to play is a strict aligned setting and play a CE character, specialized in combat.

When anyone finally asks
>why are you helping the good guys if you're evil?!
>Are you going to baaackstab us?
>No. I like to murder. And get away with it!

autistic/10 bait

I like CE. As in Vampire The Masquerade:
>Look I'm big, I'm bad! Ops I'm dead, how did this happen?

CE characters have very short lifespans.
