The Unabomber died by suicide, AP reports

He will still be remembered as a brilliant but mentally ill person who was terribly abused and ended up turning into a terrorist who hurt a lot of innocent people which only resulted in suffering.

Some misguided, confused or immature individuals might temporarily idolize him but hopefully they will end up growing up (in any and all senses) and realizing that two wrongs don't make a right and that this was most likely caused by a lack of understanding and support from the rest of the society which is a growing problem nowadays.
