In brief: No

some babies are clearly born with different personalities from there is sibs, but there is no identifiable genetic linkage.
It probably is all environmental influence. Sociopaths for example usually have a mother who wants nothing to do with her children and deprives them of love or affection; they may grow up self-centered, cruel and narcissistic.
