Atheists: Quick, stupid questions

[Lestat]

why would you worry about anything here on earth when you think there's an eternity waiting for you after you're dead? why worry about piddly stuff here on earth (and isn't it all piddly considering this doesn't even represent 0.000000001% of your existence)? who cares if the planet just blows up. why not just kill yourself and all your loved ones today so you guys can get to your final destination which is a far better place?

stupid questions i know but serious though
