Something that bugs me with the "Killing Grand/mas" page?
It's that they are casually talking about killing females (mother and grandmother) in order to stop males. You know, instead of killing Hitler and Joker themselves when they are babies or something, or even throwing in fathers and grandfathers, they are completely focused on killing the female ancestors of these two men. Even when killing a male ancestor or the villain themselves would have the same effect.
Kind of the phrase "She got herself pregnant" (something that have gotten teen mothers expelled from school, while nothing is done to the father).
