Senior Chief Petty Officer. Starfleet is in my blood, and I've spent my entire adult life in service to boldly going.
Keiko and Molly are my favorite humans, but Transporter Room 3 will always be my favorite.
Just don't ask who what's in the pattern buffer.
There's a pretty simple test, IMO
Ask a person "is bombing a school filled with children okay as long as the end goal brings about the end of the world?"
If they answer "yes" then just immediately drop them into a meat grinder and use the remains for fertilizer.
Maybe it's my cynical side, but I genuinely don't think people like that can be fixed, so while it might be considered "cruel" it's better to just put them out of everyone's (including their own) misery, a "nuthouse" just gives them a place to congregate and keep trying to spread their hate.
