I play a lot but im probably one of the least violent persons out there.

Video games breed violence isnt a myth, but nor is it true. Nice writeup on this

Generally there are other things way more effective at making people violent (Bad childhood & peer influence)

I say it again. Video games are there do make things possible that you cant do irl. For example being violent without any trouble.

Anyone with a healthy mind knows you cant just go GTAV on everybody and expect not to be put in jail for a long time.

Just like Another said. Fight or flight. Its in our genes.
