In the season two episode of Star Trek, “Wolf in the Fold”, they discover that there is a non-corporeal entity that has been going around the galaxy committing murders for a very long time. During their investigation, they discover evidence to implicate the Argelian chief city administrator Mr. Hengist.
In the end, they transport him out into space to eventually die, but before they got him to the transporter room, the entity had jumped from person to person. It was simply by chance that it jumped back into Mr. Hengist before they caught it and transported it into space. Just a moment earlier, it was in the prefect Jaris, and before that, it was in Scotty several times.
It seems arbitrary that they chose to kill it instead of trying to contain it and try to find a way to extract it from Mr. Hengist.
This scene made me pretty mad because it was really selfish and callous. Would they have jumped to beaming Scotty out into space or bothered to try to extract it?
Did I miss something like that Mr. Hengist never existed and it was just the entity in disguise the whole time, or did they really just kill him without even trying to get it out?
