There are quite a a few psychopaths who were indeed born that way. A lot of people are a product of their environment but there are still some people wired wrong due to poor human body cable management. I'm not saying null is either or, just that it is a thing that happens.At this point Josh is irredeemable, but no one is just… born that way. Josh was made by his environment to be who he is today. And I’m not making excuses for him, he still chose to follow this path, but no one is born an insufferable faggot like Josh.
And while it is normal for teenagers to “experiment,” the fucked up vile shit josh was around undoubtedly gave him some VILE fetishes.
