I'm always very torn on the issue of the death penalty, and on assisted suicide.
I don't think they should let him commit suicide because he hasn't got a terminal disease like pancreatic cancer that has reduced his quality of life and where he lives in daily pain.
One could argue that he deserves the death penalty because he killed innocent children. But the UK doesn't have the death penalty.
So it would appear he is being tortured by his conscience on a daily basis, that's why he takes overdoses. It's partial justice to live in your own hell on earth.
