Hmm, not too sure Marvin used anything for evil. Sounds more like just another example of the concept of imminent domain gone horribly wrong (and NOT used for the purpose it was intended for, what a surprise huh?) resulting in one seriously pissed off man refusing to just lay down and roll over when he was defeated by an unfair and unjust legal system.

I think we need more Marvins and fewer examples of what drives folks like him to take such drastic measures to "level" the playing field, and yeah, the pun was intentional
