I know the question sounds subjective, but literally any outside opinion would be better than nothing.
I don't have a lot of experience with D&D, I have yet to play a single game because I could never (until now) find a group of people to play with.
I'm thinking of making a fighter with a tendency to take trophies from enemies and if possible use said trophy as a weapon.. and I'm not talking about "this is my hat now" kind of trophies.. but more the "I rip off the golems arm and use it as a club" kind of trophies. The Alien vs Predator kind.
considering ripping a dead tieflings horns off to use as daggers doesn't sound very lawfull, I was thinking "that sounds pretty chaotic if you ask me"
and I don't like being a massive d*ckhead or a goody two shoes, so in terms of morality I'd say neutral.
the way I keep describing him to myself it sounds like Chaotic Neutral, but I've read that alot of DMs don't like CN because people tend to play CN as the "I do what I want" kind of alignment.
while this is not entirely wrong... I tend to do what I want as long as it doesnt hurt anyone... so no burning down taverns or stabbing quest givers in the back. removing a corpses shin bones so I could later grind them into shanks "technically" doesn't hurt anyone since they're already dead.
