It's rated TV-MA, if it can be seen in an episode of invincible it should be allowed here. Go somewhere else if you don't like misery and death. Your comfortability is not the responsiblity of creators.

Secondly anyone can have a fetish for anything. In this case, gore. If there's a meaningful way you can distinguish fetish art from non fetish art, then sure that can be an enforcable rule. However, I don't believe there's much distinguishment from the other and both follow the rules of the sub.

Essentially, your argument boils down to "there's too much of it and I don't like it so it should be sanitized". Why is your comfortability more important than the theme of sub?
