Diana's description of how she didn't kill Genocide bothered me too. The scene in the comic where she did it did not. Genocide was going to die in a horrible way- in pain, and suffocating to death underwater. Just the way Diana described it gave me the creeps. The way she killed Max was quick, clean and humane, meanwhile. So I had no problem with her going back to rescue Genocide, it seemed true to the Amazonian ideal of mercy kill.
But her description here- yeah, it seems like she's drawing a paralell to Max, and that seems really wrong. Wondy would have no problem killing Genocide. Maybe the argument was that there is a chance Genocide could be redeemed, while Max admitted under the lasso he would never stop? I dunno, it would be something to ask Gail about.
As for the AI, that didn't bother me. It just seemed she was commenting it was Ivo's, so it wasn't sentient, especially since it explained it's mockings as a "cruelty algorithm". Normally, Diana wouldn't kill someone for petty crimes such as cage fighting, especially when she didn't feel that threatened.
