Here's my list of top bad decisions:
1. Kirk's decision to leave Khan and the Botany Bay crew on Seti Alpha 6 and never having anyone ever checking on them. All the people who died as a result of Kirk's decision, are Kirk's fault.
2. Kirk not raising shields when Reliant approached. Sure he had no reason at that time to suspect Khan was commanding Reliant, but he could have followed regulations like Saavik recommended. Blood is on Kirk's hands on this one.
3. David Marcus' decision to use proto matter in Genesis. That is a pretty huge f*ck up. Not only did this result in an unstable Genesis device that created a planet that explodes prematurely, it freaks out the Klingons, and could have easily started a war.
4, Janeway never asking Q to return Voyager to the Alpha Quadrant. How many times did Q pop up? Seems to me, by helping Q raise Q jr, if Janeway had asked to return Voyager to Earth, Q would have happily obliged.
5. Picard trusting Ensign Ro. Hell, she should never have been reinstated as a starfleet officer in the first place.
6. Commodore Decker's decision to beam his crew down to the planet, only to have them eaten by the Doomsday machine. Like someone before me stated, if the Constellation were disabled, it was no longer a threat and would have been ignored.
7. Captain Tracey. Basically everything he did in Omega Glory. From not following contamination protocol, to violating the Prime Directive and arming the Kohms and personally slaughtering thousands of Yangs, to just straight up turning evil and betraying Kirk and almost murdering him.
8. Picard not uploading the Borg virus in I, Borg. At that time, there was no reason to believe that the Borg could be reasoned with, and they had tried to invade Earth once already. All the deaths from the Borg in the AQ, and possibly the DQ, were because Picard made the wrong decision.
9. Spock's decision to race off to Romulus, and try to be the Romulan version of Surak, without telling anyone. What a complete screw up that was, which almost gave Sela the means to invade the Federation. And for what? Romulus never even reunified with Vulcan. Sisko had to trick the Romulans into jumping in on the side of the Feds during the Dominion War. In Nemesis, the Romulans and Vulcan had no indication of any attempts at unification. In fact, by Star Trek 2009, little had changed, and Romulus explodes. The End. So, Spock's efforts in Unification are wasted.
10. This is pretty much a catch all for every other Captain or Admiral who went rogue or evil (IE Captain Ransom, Admiral Marcus, Admiral Dougherty, etc).
