I've already said how having a higher body count doesn't necessarily mean you're worse (Sandor/Tormund, High Sparrow). But Jaime clearly is ok with blowing up cities if it's his side doing it, so he doesn't have much of a moral high ground.

And even if you want to argue that Dany is worse, Jaime is still a shitty person and it's still ironic condemning her for hurting children when he pushed one out a window,

Plus, Dany hasn't raped anyone last time I checked.
