Hated him in the start, loved him by the end. He definitely gave off 'the worst guy you know just made a good point' vibe. Textbook good gundam character development.

it's like he was specifically crafted to be annoying with every breath he takes it still amazes me to this day kai fucking shiden is less of a bum than this graggle simpson prick

I think his death was some redemption to his character. He was insufferable but he definitely cared a lot.
