You can stop reading now then.

damn bro even i don’t hate mort that much, noah isn’t entirely innocent either, if you don’t like it don’t read lmao

As the line goes, "Lighten up, Francis." Mort's pretty vile, yes, but that's the POINT. At this part of his arc, he's got the exact mindset of a solitary predator, generously mixed with sadism. It's a horror comic as well as a vore comic. And Mordecai is a pretty darned good horrorbeast. If the heat's too much for you, get out of the kitchen.

Noah did invade his den and attack him in the first place. But I suspect a lot of this is just that fire-demon temper tantrums, rather like their lifespans, last a very long time.
