How do I feel about someone who almost caused my death?

Ok, I made this account just to actually ask this, I don’t know who else has been in a similar situation but, a few years back, I was incredibly sick, I was misdiagnosed several times, and my father believed I was faking it. He attacked my mother several times and refuses to acknowledge he was wrong about me, even now that I’ve got POTS from the damage to my body. I know that if people listened to him, I would never have received proper treatment, and by this time, I would be dead. I feel like I hate him, but, I want to know what you all would think, if you were in a situation like this, I’m sorry if this is too serious for this site, anything you have to input, I’ll appreciate.
