Whats good and whats evil? I think most people have a compass built right in, a conscience, that kinda tells you whats good and whats evil.

Generally, we do not like bad things happening to ourselves.. and if we see things being done that we do not like happening to us, its evil.

Are everyone good? of course not.. thats why we have sociopath in society.

definition :
A sociopath is a term used to describe someone who has antisocial personality disorder (ASPD). People with ASPD can't understand others' feelings. They'll often break rules or make impulsive decisions without feeling guilty for the harm they cause.
