In the event of destroying the data, Eve, will die in the mission Priority Tuchanka in Mass Effect 3.
Once that’s been dealt with, you’ll have the choice on what should happen to the data, and the choice you make here will have direct consequences for a character in Mass Effect 3. Near the end of Mordin’s Loyalty mission Old Blood, you’ll enter Maelon’s Lab, here, you’ll get a scene of Maleon scanning a holo screen with an Omni-Tool, Mordin will confront him, and Maelon will tell him his hands are already bloody, but it’s worth it, if it can undo the genophage, mainly because he sees the Galaxy better off with the Krogan than without them.
