I'd say that the MCU does not have a good track record when it comes to parental figures (mostly).

Odin was deffo someone who tried to explain his actions (setting his sons against each other, hiding any evidence of his firstborn until the last possible minute, ignoring actual!threat (the Dark Elves) because he refused to even admit the possibility, etc) despite how, when seen collectively, they were on the TERRIBS scale.

However, the absolute worst (aside from Thanos who was shitty AF) was deffo Ego. There's nothing about him that one can overlook/handwave.
