Review Detail of Xymn in Holy Necromancer: Rebirth of the Strongest Mage

I really enjoy the writing of this story and the whole power working of all the elements, except death I find it a little weird for it to have its own element. There is nothing wrong with that and still makes the story find even when he gets the dark element mark as well, but my biggest problem I found was when he betrayed the Dark Church Origin Mark holder. Like it made no sense like mc said ‘I see that she looks down on me and sees me below her.’ But I have never seen that in the story and acts like a total dickweed for no reason to her after betraying her the mc makes this dumb decision out of nowhere and then he justifies it with “She looked down on me”? It makes no sense, like it seemed even the one got betrayed show more logical and realistic character traits of that moment. Idk this one moment really killed my whole liking of mc and killed my momentum, for now it’s dropped will pick back up in like a hundred chapters or if it finishes.
