Is it because you believe the myth that high testosterone causes violence? That "roid rage" people normally picture when thinking of people who do steroids is actually people who neglect or don't put enough effort into post cycle therapy or aromatase inhibitors to LOWER their estrogen levels.
Yes taking steroids greatly increases Estrogen levels as well and this is the main reason many men who have done steroids without proper cycling have some semblance of breasts...
If anything this "violent" society you speak of is most likely a result of these pseudoestrogens / xenoestrogens and other endocrine disrupting chemicals.
