A win is a win. Why would it be wrong for a player to resign a move or two before a forced mate? What's the point? Both players know how the game will continue, isn't it more responsible to end the chaos and bloodshed? ;)
As usual, this wasn't really the point. The OP's opponent played on while the continuation was NOT certain, and resigned when it was. The OP took offense that the resignation did not come earlier.
