"Are we to say that any individual who's on steroids that has an angry moment is due to steroids? What about the individual who gets angry and kills someone who's not on steroids? What do we blame it on now?"

Jose Canseco's quote is questioning the idea that steroids are the reason for a person's upset moments. He is recommending that if somebody on steroids has an upset moment, it is not necessarily due to the steroids. He is likewise suggesting that if somebody who is not on steroids has an upset minute and kills somebody, then it can not be blamed on steroids. He is suggesting that there are other elements that can cause a specific to blow up and act out strongly, which blaming it on steroids is not constantly the answer. He is suggesting that we should take a look at the person's environment, mental health, and other aspects that could be adding to their habits.
