Exactly, it’s not like Trump himself is a fundamental Christian with misguided but deeply held convictions. He is a narcissist that wants adoration, power and to be in a special position where you can dodge consequences.

There is actually a huge thing to consider with any kind of authoritarian system ideologically: Basically without fail, they will have a “rules for thee, not for me” dynamic behind the scenes. Make abortion illegal? It will still be possible to skirt the rules for the powerful, and pervert the right to control your own body as a woman into the privilege of powerful people - mostly men - to decide if they allow a pregnancy to continue.

Authoritarianism lives, psychologically, from having the people on top, the ones “worthy” in the eyes of ideology, being able to bend or fully circumvent the rules. Even today, this is clearly visible in how rich people, and even more so rich organisations, are treated differently in front of a court, where proper consequences seem to be an exception instead of the rule. This also shows in more fundamental, everyday mechanics of society, think of how the violence monopoly of the state more often than not rests on the tacit acceptance of excessive police violence. Where often, cops and paramilitaries in police roles within states are developing a self-image and identity, along the lines of “to protect society from itself and its horrendous violence, I must become a violent badass” - consciously or unconsciously enjoying the violence and control they can enact, or turning their heads when their colleagues do it, and reserving for themselves and their in-group the privilege to do so.

So, having someone like Trump, a clear narcissistic rapist, being both openly against abortion rights in his political platform while personally holding the belief of abortions being allowed, is no real contradiction at all. He can rest assured that if in power, he would have the privilege to force both consensual mistresses and victims of his assaults to have abortions anyway.
