Do you think steroids impede on peoples judgment and common sense?

Just wondering what the effects of Steroids can be on you mentally and emotionally? Someone I know is trying to use short term steroid use as an excuse for some pretty bad behaviour and most of the information I can find surrounding this drug is all directed at aggression and testosterone, not the ability to cloud someones common sense or alter there personality drastically in a short period of time? Fair enough long term use can lead to some serious health side effects and aggressive behaviour with increased hormone levels but this all seems to suggest it's over long term use not just in a few weeks?
