Deal or no deal?

Where do you stand on making deals at the final table? Before I made any I was dead against them, but I’ve made a few recently and as soon as it’s down to the final three I’m usually the one suggesting the chop. I’m fairly confident in my endgame but I seem to want to lock in safe money rather than play on and potentially lose a fairly large sum of money. Everyone is normally agreeable and the chop done according to chipstack sizes, but do you think it can have a negative effect on your game if you’re thinking about deals as opposed to winning the game outright?
