Are GPs born with the sucker gene?

By way of background, I must state that I am pissed off with the world in general and Homo sapiens in particular.
I am not depressed, but I have long realised we are a flawed species.
Our DNA, with its many mutations, has resulted in our species being very complex and very competitive.
Sadly, because of the latter trait, we have a terrible track record of treating each other very badly.
