Tarmor's Terribly Tantalizing Tarasque Terrrifying Random Banter #234

I consider myself a rampant egotist, and yet this is in the running for the most egotistical thing I think I've ever heard.

We have an expression over here "Après moi, le déluge", "After me, the flood."
It means that somebody is so unconcerned about the long-term consequences of their actions, as long as they happen after their death, that wouldn't care even if it caused the world to end.

Don't you have something similar?
