Yeah, you dont know if that would happen. You can at least try to get Vido later on.
You DO know that Vido is a bloodthirsty evil bastard. Make no mistakes, he WILL cause more deaths. Considerably more than the amount of refinery workers.
Better to take him out now that I have a chance. I might save lots of people by doing that. Or I might not. That's the chance I'm willing to take. Hell, this choice pales in comparison to the Collector base. For all you know destroying it WILL make the Reaper war a lot harder for organics. And yet you decide to destroy it.
When it comes up in ME3 that this caused deaths of millions of living creatures, will you still think it was the right choice ?
You must be ready to take the risk.
