Never make decision when you're angry because at the end of the day, you will regret that decision.
Some says whatever is said during an argument should not be taken to heart as it does not really matter.
However, some also says when a person is angry whatever is said is the hidden truth. What they truly meant.
Whatever it is, I suppose we should never make a decision when we're angry. We should still try to think rationally during an argument.
