Playing an evil char: how well would that be received form the community ?

Well, it sort of depends on how you define evil.

If you intend to RP an evil personality - a truly evil, diabolical villain type thing, I think that'd be quite fun. The whole twisted and scarred backstory, slightly insane overlord style is an entertainment.

If you mean to act in the ways you described above, I believe you'll find there are already people in game who act like that, or are percieved to act like that. You'd probably get the response of being called a jerk every now and then.
