An irrelevant story

Long long ago there was a very good man. But there were bad men too, as always been. One day, for some reason bad men took the good man by force to a bad place. They proposed three evil things to do to the poor good man. He should choose and fulfil one of them. Otherwise, they would hurt, even kill him. The first choice was 'killing a man'. The second was 'raping a woman'. The third one was 'drinking alcohol'. They told the poor good man: 'Kill this man or rape this woman or drink this alcohol! Choose one!'. 
The poor man started to think on the choices. He cannot kill the man since he didn't kill even a fly till now! How can he kill a man! In addition,  it would be choosing that man's life on behalf of his life! No, this is not the right choice!
Raping a woman? Impossible! Honour is one of the most important things in this world and he cannot shame a woman like this. Also, he cannot live with this shame in his remaining life.
And the last one: Drinking alcohol. Although it was not a good behavior which everyone knows and he never did that before, but it seems as if the best of those evil choices. And by this way, he wouldn't hurt anybody else; neither the man nor the woman. Yes, that's the best choice!

Then he start to drink alcohol. When he is finished, he was drunk now. And since he was drunk, he wasn't able to make the right choices as in normal life. Then, after drinking it, he killed the man also. And then he raped the woman, too.

So what is the worst of evil things in the world?
