Vincent probably didn't shoot himself, I'd rather we didn't dig up their graves: https://pubmed.ncbi.nlm.nih.gov/32732590/
Suspiciously Theo dies soon after: https://pubmed.ncbi.nlm.nih.gov/20051145/
And a distant relative killed: https://allthatsinteresting.com/theo-van-gogh
I never knew how they died, took a Van Gogh cartoon to educate me tonight because nobody tells me nuthin! (Le film: Loving Vincent)
What's the end goal? Inflate the price of his art to profit?
Possibly, could even be jealousy, heat of the moment stuff, I think he knew who it was. Killed the brother for being suspicious and having claim to profits. I really don't know, I'm still thinking it over.
