What exactly did he do to deserve to get gunned down by a madman?
It all depends on what form of karma you're discussing. It can be argued that his death was a form of punishment for actions in a previous life. Some believe that karma is like currency, finite and gets spent, and to those it could be said that the good experienced by Lennon far surpassed the amount of good he did to earn the karma.
Even if just by the more traditional view of karma, and looking at just that life, it could be that Lennon did bad things to earn the bad karma that caused his death, and those things just aren't public knowledge. For all we know, he struck a pedestrian, took off, and it was never linked to him for one reason or another. We only know one facet of his life, so can never say if it was deserved or not, by the karmic system.
