I am really sick in the head for liking the ending

I assure you, you're not. It's actually a befitting ending for the story for 2 reasons
1) Sura is a god of war whose very existence means destruction, domination and death. So, Choah's fate was sealed when he caught Sura's attention
2) Their fates were intertwined and no matter what they did, they are bound to be together.
I think if you can see it this way, it makes it easier to accept the outcome.
I really need a therapist.
Never in my life i thought u like something like this and i need therapy too( ̄∇ ̄")
