Which also indicates that the use of the thing is rather (pun not intended but unavoidable) limited. If it works on stress levels - i e people who kill under stress or intense emotion - anyone who kills disapssionately (like Blake, for instance) would have no trouble circumventing it :-)
I wouldn't say that Blake is dispassionate about killing, more that any killing he does is part of a plan involving rational objectives about which he feels strong emotion.
BTW, although I'm certainly not the world's greatest Blake fan, I think he's a good enough judge of character that he would not treat a maniacal serial killer as a valued shipmate--and nobody else seems frightened of or disgusted by Gan when his limiter isn't malfunctioning. Some of Blake's extreme grief in "Trial" is caused by the loss of any crew member--but a lot of it is due to Blake's respect and liking for Gan as an individual.
