That’s called metagaming. In NetHack you would see people drinking from fountains all the time in the early game. Occasionally you’d get a wish which you could spend on some powerful artifact or silver dragon scale mail (SDSM) and win the game. Most of the time you’d unleash a bunch of water moccasins or a water demon and die immediately.

Needless to say you could win games of NetHack by doing the metagaming strategy. The problem is that it wasn’t going to help you win the current game in front of you, the one you’re playing right now. And that’s where some players (like myself) part ways with metagaming. We are interested in winning the current game. That is, taking every game as a unique puzzle to solve and attempting to win. So a game that randomly decides “haha you lose” is unsatisfying.
