Several million human beings died in The Holocaust because a homicidal sociopath decided that they didn’t deserve to live based solely on their religion or sexual orientation or mental abilities. Even though these people did not in any way affect Hitler or the way he chose to live his life, he had them systemically enslaved and murdered. In contrast, several million fetuses are aborted every year because the women carrying them decided that it wasn’t in the fetus and/or the woman’s best interest to bring the fetus to term.
Hitler did think that the people he murdered were affecting his interest negatively. They were in his way. They were inconvenient to him reaching agendas and goals - same reason some choose abortion.
