The most interesting and smart thing about chainsaw man part 1 (TO ME) is that Denji believes women are purer and better than men. Hes abused and controlled by men in his childhood and has literally never had an adult male figure in his life care for him or his needs, and it makes him think men are evil. he doesn't like hanging out with guys, he doesn't want to be touched by guys, he subconsciously distrusts them all. Conversely, Denji trusts women implicitly. Every woman who walks into his life he allows in with little resistance, Himeno was not a safe person for Denji but he had absolutely no clue that she could hurt him, nor would he even consider that she could hurt him with sex. Because sex with a woman is what Denji thinks will make his life right, what he thinks can fill the emptiness. Power attacked Denji, Reze attacked Denji, Himeno tried to kill him and he still let her closer to him than anyone had ever been before. Makima most of all, even when Denji wondered if she was a good person, even when she began to take his happiness away, Denji allowed Makima close to him. This isn't to say Denji is to blame, like i said, hes wrongfully come to the conclusion that men are evil and women are good. Even when he figures out the women around him aren't exactly what he was hoping for, he continues to trust women and distrust men.
See: callous and dismissive towards Yoshida, then instantly accepting Asa's proposal.
This to me is so interesting, its a really well thought out aspect of Denji's character. It honestly does subvert a fair amount of story telling tropes. These women are just as evil and manipulative as these men, and that is fairly realistic. Women are not paragons of kindness and motherly affection, they are just as violent and cruel as any human has the capability of being.
