Maybe you aren't a native English speaker, so this is a misunderstanding. Despite what it literally means, "to undo" in common English usually just means "screwed over". If he had been convicted and was alive he would still have been "undone" by this video

I'm indeed not. Thanks for clarifying, and it could be, but I still think it has a double meaning. Especially in this context I think It's just insinuating and sensational.

I've actually never seen this wording being used ever, so for me it seemed quite similar to "doing someone". Yes that also means "screwing someone over" but for me, when reading "undid" a quote from the movie Trainspotting came to mind.

"Begbie didn't do drugs either. He just did people" and that involved a knife usually.

/edit: Considering the dictionary's definition I will hereby withdraw my suspect of any intent by the author to suggest that another person or entity was responsible for Aaron's death :)

From the Oxford English dictionary: undo - cause the downfall or ruin of.
