Revenge…
For many people, it's the fire that lights them from within, but when its target is too distant, it leaves only cold despair.
Besides, revenge on who?
Malzahir suspected that whoever killed his grandmother was likely acting on the behalf of someone far more powerful—possibly even Lord Sirakhim directly. And if not him, then one of the few figures capable of opposing him—another demigod.
Not to mention as long as the person that did the action was even the weakest beast-tamer, he wouldn't be able to exact his revenge—he was 'crippled' now. Completely vulnerable to even the weakest of spiritual creatures.
He didn't even dare dream of exacting his revenge on Himolker.
'It's only in delusional fair tales that an ordinary person would be able to take down a high-level warrior.'
He saw no hope of ever achieving justice—therefore, he saw no reason to continue living in this world where he'd have to be confronted by his dismal reality.
