If we can take cryonicist Jerry Leaf's account at face value, he assassinated people for the U.S. Government in Southeast Asia in the early 1960's. I got to meet Jerry two or three times and exchanged some small talk with him before he went into cryo in 1991, so I don't claim I knew him or anything beyond that. As I recall, he had some kind of military rifle on display in Alcor's facility in Riverside, CA.

Now, if Leaf had actually killed people with his own hands, does that fact make him a "bad person" who didn't deserve to go into cryo?
This month's media thread includes a short article on some people's idea to have Ayn Rand frozen, which ultimately didn't happen. My first reaction was a shudder. I thought, I definitely wouldn't want Ayn Rand preserved forever. My second thought was, What right do I have to say who can and who can't get frozen?
Whatever your thoughts on Ayn Rand, I think this can spark an interesting conversation: What, if anything, should humankind do about people who are widely seen as harmful for the whole? For example, if the Castro dynasty in Cuba or the Kim dynasty in North Korea decide to freeze themselves to ensure they will continue oppressing their countries forever, should that be prevented? (And yes, my opinion of Ayn Rand is such that these examples came to mind.)
