You don't have to capture it, you just have to move it out of the way so if you faint it then it's not a problem cause the path is no longer blocked
Yes, if you faint Lugia in "Pokémon HeartGold" and "Pokémon SoulSilver" then you will get another chance to capture it. Once you faint it, you have to go beat the Elite 4 and the Champion before it'll regenerate.
It is gone. If you saved the game after you killed it then it is gone forever.
It will come and kill you in your sleep. Goodnight
