It depends on the Krogan leader if you have Wrex or Eve alive cure. If Wrev rules alone, sabotage.

(voting sabotage as my canon Shepard had Wrev ruling alone.)

Only under Wrex Do they deserve the Cure since Wreav would have started a second krogan war with the cure. Anyone who says that curing the genophage is wrong either way think that

the krogan should just die out.

I cure the genophage. I'd call it a human rights violations but, we're talking about alien species.
