Well, it depends. If you are abusing your body by drinking too much alcohol, then yes, sometimes it can be reasonable to blame the alcohol on your actions.
Hey, you chose to drink so therefor it is your own fault. Think about... If you stop drinking you might not do the things you do but you were the one that chose to do it
No. But it's been used as a legal excuse before and I think it's bs.
No and if you do things on alcohol that you have to feel any way bad about when it is no longer in your system then you should not consume it
