Superman: That's for Dan Turpin! Darkseid: Who?! Superman: The good man you murdered! Darkseid: Had I known one human's death would pain you so, I would have killed more. And kill more I shall. Carry that agony with you to oblivion, Superman!

I think that exchange right there says enough. We know for a fact that Darkseid is a sadistic despot who conquers worlds and destroys civilizations for a living, but it really goes to show how despicable he is when he's caused so much death and misery that he can't even remember one particular instance, but, even so, is willing to cause even more death and misery just to torment Superman.

This is an easy yes.
