To be fair, he did also kill an entire village of Tusken Raiders, including women and children, one movie before that. It’s just that those movies are so weird and disjointed that this doesn’t feel like a piece of character building that later pays off in the third movie, but rather a weird fever dream that you forget about almost entirely by the time Attack of the Clones is finished
I think so. I remember Anakin delivering the line, “I killed them all. Not just the men, but the women! And the children!” in such a ham-fisted way that I actually LOLed in the theater. But I also haven’t seen those movies in at least 10 years.
