Q is just a dick. He could’ve brought Voyager back home but didn’t and then involved Janeway in that continuufederacy civil war. He exposed Picard and crew to the Borgs and didn’t lift a finger when he got Locutussed. I think in terms of dead people he may have screwed Picard over more. I may be wrong but I think more people died in that cross section being cut out by the Borgs as a direct result of Q finger snapping the D out to meet them. But at the core, he just does stuff because he’s a bored omnipotent dick and he makes everyone in his path suffer.

At least Picard wasn’t impregnated.
