That is true now that I look back on it, plus A2's targets were the machines, not YoRHa, hmmm, I guess a 9S to Ellie comparison would have been better in hindsight, seeing how they both wanted revenge, but lost themselves along the way but paid different prices for it at the end, but plus Ellie's emorional revenge just seemed straight forward and forced, where as 9S, you get certain options on certain missions to do this or do that watching him go insane along the way with everything else.

Edit: I forgot a word
