Thor knows that if anyone had given him the choice to remember everything or the choice not to, he'd choose the latter in an instant. He harped endlessly on Valkyrie about running toward her problems and not away from them, but in the end, he was just as guilty as she was.

Thor had truly believed that he was running towards his problems when he went on his suicide quest to kill Thanos, but now, it felt increasingly obvious to him that he had been running away from them. Thanos had won and Thor had come here and with no immediate objective to focus on, all that remained were the feelings he was avoiding. Anger, guilt, loss, regret.

Even now, he didn't want to face them. Physical pain he could abide; he'd spent centuries building up tolerance. Emotional pain was considerably newer. He didn't know what precisely to do with it. It materialized in unhealthy ways, like charging towards his ally and lifting him up by the throat or striking a man capable of wiping out the galaxy in the chest instead of the head just to see him suffer.

Or finding some reason to clash with anyone who might push him to confront them, the way he did Valkyrie.

"You ask me to tell my brother and when I inquire as to why you suddenly find it important, you tell me that you would want to know."

Thor exhales in a sound that doesn't quite make its way to a breathy laugh.

"Is that really it, Stark?"
