Well i can tell ya all from firsthand experience as a steroid user that they will effect your state of mind. Theyre a hormone after all. When im running a cycle i get aggravated very easily and my normal jealous tendencies go thru the roof. And i dont take nearly the dose that these(Pro Wrestlers) guys do. In fact, there are certain steroids that are used to increase aggression (cheque drops for example) that im sure these guys use to increase their performance in the ring.

Furthermore, if he was already suffering from a mental illness, steroids will just magnify it.

It will be hard to make a direct connection as the testosterone didnt literally jump out of the bottle and strangle the wife and kid but in my mind it definetly played a role.
