Solitary confinement in general is out of proportion, particularly for extended periods. In my opinion it should be a violation of the Eighth amendment and they need to shut down Florence, but few people fight for it because it's full of really wicked humans. Important to remember they are still humans and torturing them is not okay.
That being said I also think that the life sentencing was probably appropriate considering he started the silk road as a fully grown man, so it's a clear reflection of his morals and empathy. It's difficult to think about how many addictions, overdoses, and so forth that he helped to enable, in addition to assaults and murders (silk road sold weapons and services). Not saying that it wouldn't have happened without him, but certainly enabling these things to be trafficked does not provide net positive to the world.
