Okay. I'ma do it. I'm going to say the most controversial thing I've ever said on here so far.
Sisko is my least favorite Captain by a significant margin. Him making a planet completely uninhabitable for humanoid life and forcing refugees to flee again is a seriously big reason as to why I don't like him. The whole assassination plot is another reason, although that's open for debate. Sterilizing a planet for centuries just so you can hunt down a single man? One that you have a personal connection with? One you clearly have feelings of vengeance over? I can't get with it.
