A prince my father believed in? An Avenger who has never let you down?
I was a bloodthirsty, angry, prince ready to go to war over the slightest transgression with a nation my father had brokered peace with. I was an arrogant warrior prince who got banished because I was becoming too much like my sister the Goddess of Death. I, that same prince, became King and my first action was to literally destroy the entire planet that my people lived on. Intentionally. In a move that even Loki was hesitant of. My second act was to deliver them to Thanos, where he killed half of them before I could even evacuate them. A terrible Prince that became a God-awful King.
The Avenger? Couldn't do anything when it came down to it, could I? I could have killed Thanos when I had the chance, just like I did when we saw him the second time. I could have easily driven stormbreaker through his neck. Instead, I wanted him to suffer like he had made me suffer, like he had when he tortured me with the power stone, like he had when he strangled my brother to death while I was powerless to stop him. Because I was selfish, because I wanted that satisfaction--- he lived. And he snapped. And I became responsible for the death of every man, woman and child who dusted. Just like that-- my selfishness had doomed so many people to their Death.
The two planets I loved, the two homes I held, have been utterly destroyed by my choices. this is why I stay in my hut.
Maybe I'm not like him, this other universe me. Maybe I'm worse.
