He was disillusioned with society, and wanted something better for himself, and believed he would find that internally, in an isolated spot in the wilderness. But he didn't think it through, he was idealistic, and sadly he got his wordly wisdom (that life is nothing unless shared with others) on his death bed. I don't think he was a dumbass. I think he was just young, and a dreamer.
I also think he had a death wish.

"Sometimes eating the wrong food with the right attitude is a better choice than eating the right food with the wrong attitude... That’s how powerful the mind and the heart can be in the healing process."
