In my value system, people should be able to achieve much more alive than dead. One's own death should not be more effective at reaching terminal values even if life isn't a terminal value.
My value system also says people should have as much time as they want to achieve what they want to achieve, up to and including infinity(ies) if any such quantities exist.
And on top of that: For me, "life" is a terminal value. Each human mind forever lost substracts large amounts of points from the total potential utility I compute from possible futures of the universe.
While I agree that it is suboptimal (and tragic), his death may save/extend more lives. The effect seems to be making more information (especially scientific information) freely accessible, which in turn seems likely to result in more innovation and better access to treatments as they are developed.

He deserves a eulogy more eloquent than what I am capable of writing. Here's Cory Doctorow's, one of his long time friends.
It's a sad world in which you are being arrested and grand jury'd for downloading scientific journals and papers with the intent to share them.
