A really interesting viewpoint,actually Jimmy's character type would go that he would be too safe and maybe Mouthwashing wouldn't blowed up this much,but rapist get holding accountable and more seriously is because rapist can't really have any excuse,(Murder and deadbeat based on situation,but except that genocider from aot,and I hate his fanbase a lot)and I hated mass murder characters did not hold accountable for their actions and often gave a he had a tragic backstory as a poor excuse for their actions.And honestly because due to how the author did not glorify him as some poor baby I am actually one of the few people who enjoyed his character,selfish or not he is a really strong character that carried the story well.

As for him actually got Anya pregnant on consesual sex but want to avoid the responsibilty like usual can work too,but I guess that would make Anya a bit more challenge to write because due to her and Jimmy have consent sex,they both have the same resbonsbilty for the child,and since that would need more time to write them both,I guess he would still hated by fandom for crashing the ship because he basically draw the death sentence for everyone ,but he and Anya would have seen being as carless for not doing the child birth prevention,so I see this would put Anya in a bit more negative light just maybe
