I disagree.^^
"Jetrel" is among my top 20. Actually an example of a good, touching story. Not to mention how Neelix's tragic background was revealed.Suddenly the character had another depth than being just the comic guy in the set.
Jetrel was terrible. The guy invented a device that killed 400,000 talaxians...if one photon torpedo was detonated in San-Francisco how many millions of people would be killed?
He also did it to protect his race. We learn in the episode that Neelix didn't fight in the war because he disagreed with how aggressive Talax was being. Hmm wonder why Jetrel may have felt motivated to create a weapon to counter aggressors. The writing was terrible, from the get go we are only allowed to think Jetrel = Bad Guy...no wiggle room. Star Trek is at its best when it isn't ramming down our throats what we should think...
I think many Trek goes out of it's way sometimes to show "bad guys" have a human compassion for things outside of their cause. However, Jetrel did as he was told during a time of war. How do we know that dening his government wouldn't black list him as a traitor? The fact that he had guilt over what he created showed that even bad guys have compassion. Let not forget during war it was America that dropped a bomb on the Japanese. Too many innocent Japanese people, we are the face of Jetrel.
