This might be a little unpopular, but I find the story of Marvin Heemeyer to be most tragic because of his failure to exact his revenge. He did millions in property damage, but it was *all* insured. Hear me out: Yeah, he smashed the house of the asshole who wouldn't let him hook up to the town's new sewage system (on his own dime/labor, no less) in order to avoid an absurd fine, but what did that ultimately achieve? The bastard had insurance. He probably got an even *bigger* house/property. All of these assholes became "victims"... without becoming *actual* victims, if you get my meaning. Marvin seemed prepared to shoot people- he had made gun ports, and he had a few rifles/carbines and pistols with a hefty amount of ammunition sealed into the Killdozer... but he only shot at a few power transformers. He did not shoot at any people. This may have been because of his religious beliefs, since he had gone Christ-Insane towards the end- maybe this is why he didn't kill anybody. What I'm trying to say, is that all of these true *monsters* who victimized Marvin, a man who was nothing but a good, hard-working American who wanted to work and be left alone, only suffered a little scare at the hands of Marvin. He didn't take any true revenge and put those monsters in the ground. He absolutely could have- the son of one of his enemies was operating the vehicle that first tried to slam into the Killdozer and disable it. Marvin could've shot him dead, but he chose to drive on and direct his wrath upon material goods. **The people who wronged him survived and likely went on to fuck over hundreds, or even thousands of more people. This is the greatest tragedy of Marvin's story, for me: for all of his focus and dedication, he was not able to exact any meaningful revenge on the people who literally took everything from him.** But hey, life isn't a movie, the good guys usually lose in real life...
