[The Flash] What were the ethics around the The Pipeline prison? It's basically indefinite solitary confinement.

*edit: Thanks for all the responses and discussion. You might notice I haven't added much to the conversation, and that's entirely because I have no idea what the ethical implications would be in this case; it may be better for me to just listen than spout off on something I know very little about.*

Fascist dictatorships generally occur when people with power decide to start exercising it against those who don't. The Flash, a being of nearly infinite power (time travel, c'mon), and his then-mentor the Anti-Flash (by all accounts a major dick) decided that it was better to exercise his power over his captured foes by imprisoning them forever and "worrying about it later", rather than facing the present-day ethical issue of either killing these people, finding a cure for their super-powered mutations, or rehabilitating them psychologically. 

So basically, the ethics are "it's easier to not think about it". Also, who knows if they're being fed or not, that gas guy is probably gonna leak out of any airlock designed to allow food in.
