Both had terrible, abusive fathers?
Of course I know what you are alluding to, but I believe there is a yuuuge difference: Jackson was a pedophile in the literal sense of the word. He was deeply disturbed and tried to regain his stolen childhood by inappropriate relationships to kids (sleepovers etc). AFAIK unless new information comes to light, he never raped anyone, as weird and unacceptable his behavior towards kids might have been.
Trump is a sadist. He gets off on dominating others. That starts with forcing contractors to accept less than was agreed upon and continues with humiliating other heads of state publicly and making his political enemies swear fealty to him. And of course the ultimate humiliation he can do to a woman is to rape her and revel in her powerlessness long after the crime. Even more so if she is underage and he can get away with it.
I am not saying one is good. It’s just that the other is so much worse.
