I don't think it's fair to liken luigi to the unibomber. Ignoring that his methods were also crazy. The biggest thing to point out on the unibomber is his victims were every day people. Obviously his method was made with collateral damage as a high possibility.

Luigi, his political leanings seem to be all over the place. But at the end of the day his only victim, was someone who inarguably made choices knowing they would result in the deaths of many people, and bankrupt and ruin the lives of many more.
