In any genocide, the perpetrators always have a 'reason'. They'll always be able to tell you that the people that were killed deserved it, and that it needed to happen, and that the world is now better off etc. etc. But saying it and thinking it doesn't make it true. God can spew out justification for genocide all day. But why would I just take the word of a murderer? Especially if they are a super-powerful being who no-doubt had all sorts of other options available to them. Why would I take their word that suffering and death and destruction is justified when it is done by them - but not by others? And God doesn't even bother to attempt to explain or talk about that to me. I just hear it from you, and other fans... which makes it even less reliable.
