I understand your need to fear him, I do. But you should understand my need not to.
I've lived my entire life hated and feared, first by my father, and then by most of humanity. I lived my life afraid of my father, and doing what I had to to keep him away from my brother after I found out what he was capable of. When my mutation came to light he came after me with a ten gauge shotgun, the man that was supposed to love me and protect me wanted to put a hole in me big enough to drive a Mack Truck through. It wasn't until around this time last year that I learned that I didn't have to be afraid of him anymore. Because he was dead. And sadly so was my mother. His last victim. And he was only human.
Humanity feared me, to the point that me and the other remaining 196 were actively hunted if we weren't in hiding. They didn't know me, but they wanted me dead. It wasn't a good feeling at all.
I don't know if you noticed, or if you cared but a future version of myself was here for a short time. She left notes, and she attempted suicide by taunting your father. I don't want to be her. And I don't want your father to be the man she knew and had to help... kill.
I'm one of a few people that think he deserves your love instead of fear. He deserves to know what it's like to have someone he loves enough that he's willing to do whatever it takes to keep them safe. I don't think even he thinks he deserves it. But everyone does.
I also have something most everyone else doesn't. An animalistic danger sense. Ever heard of 'spidey senses'? They work like that. Which is one of the reasons why I'm a good hunter. I also have good common sense, one that says don't piss off Loki because that would be severely stupid. I don't have to fear him to know that.
