Its tough to control anger and deal with bad beats. You are very correct and it is part of the game, there will always be those guys that will follow it to the river just to get that one in a million shot at the best hand. I am the opposite of an angery player and I have a very similar play style in tight aggresive. Though at times I can play very slow and safe. I would have to say that the best time to play like your describing is the end especially with smaller tournys where it is more likely you will be short handed at the final table.
