First of all you cant generalize for a whole group of people.
I for one...is someone who gets less aggressive on steroids. Also happier, more patience, tolerate and just generally a better person. And i know I'm not alone in this.
It's a poor excuse that tries to remove accountability for your own actions, the appropriate answer or solution if you will, is not to shift blame over to the steroids...because you're choosing to take steroids knowing you'll become more aggressive, which again, is a totally free and open choice you as an individual decided to make.
Roid rage is a myth.
Its not like people magically get a new "the hulk" personality and seeks out fights just cuz he pinned some testosterone... It will take precisely the same amount of bullshit to set me off, the difference is once you set me off, its much harder to bounce back down again.
I take steroids to enhance my recovery, strength and ability to grow muscle at a highly accelerated rate. I dont take it to become a different person. But everyone is different, with different goals and means to an end.

Steroids to me is literally cheating time.
