In a PC, you can either use a special console command (see the Paarthurnax quest wiki) to "cheat" the blades that you killed Paarthy, but actually he will be alive, or use mods that allow killing the blades instead.

When not killing Parthy and advancing in the main questline, the quest to kill him might dissapear from the quest log and you can forget it.

In my case I try to not kill the poor old dragon. The first time, my game "intentionally" crashed while giving the first blow to Parthy. That's why I don't kill him. Instead, I bring him a friend: I summon Durnrehvir while in the Throat of the World, and imagine the two old dragons chatting, hehehe. After completing the other Blade quest, getting Dragonbane and Esbern's potion and bringing them some "useless" recruits, I never come back to their temple.
