It's one thing to break the law in a calculated way, so long as the end result will hurt nobody or is seen as necessary, and quite another to do it because God gave you permission. I think so, anyway, but I got high when it was illegal. I would argue it was necessary.
My guess about why old people get off on solitary confinement is that our world is getting narrower, or going to get narrower rather soon, so we begin to sadistically want more to suffer that fate. Humans are rather dark and selfish animals.
