I'm just glad he died because he was so freaking obnoxious.
He made Neelix likable.
To be fair, he didn't necessarily DIE
considering he was just "separated". There was no body! No corpse! He was just split back into the correct people---Tuvok and Neelix!
Let's see somebody beat out Tuvix's creepiness!!!!
Suder was pretty creepy too. And he committed cold blooded murder.
