Well it's not like Diehauser's crime is very severe. He didn't kill anyone like Diodora did, nor did he led the attack on the Underworld directly. He was just using Rizevim to expose the corruption of the current Devil government, and he had to do that because of the root cause the corruption blocked him from exposing it to the public through official means.

In a sense, he's a victim to the government corruption as well, Diehauser was forced to use the illegal way because the legal way is being blocked by corrupted politicians who cares solely for their benefits.
