For singleplayer, the player would usually reload battles lost by bad luck, but not the ones won by good luck. He ends up cheating in a sense even without save scumming.
Heartstone? LoL with random mates, etc.?
Yes, its gamers mentality - not to solve but to go easy ways. Never to use healing bottles, ressurecting scrolls, granades, dispels... better to load saved game...
Anyway almost every game have Hardcore mode to counter save scumming
