Well, the more accurate translation would be "plunder", since "steal" implies that you took the stone without the person's knowledge. But even this isn't the perfect answer - in the game, sealstone battles it's about pitting your hard-earned daemon against other person's. It's a battle to see which one of you is the better Ghost Agent, with sealstone/silvers on the line.

Having said that, I am still a bit confused as to what you're asking - are you questioning the moral consequences of these actions?
