I would even go further and add one is not supposed to make choices when extremely happy either, because both happiness and anger can both fog common sense, before we realize it, we could have committed a very serious mistake or misstep.
It is a definite fact that anger does blur judgment and creates decisions that individuals come to regret in life. One should think and relax before responding even in a situation where the feeling is strong. Your description of anger converting people into doing outrageous things actually highlights the detriment that we can have by making rash decisions. And you are right the exuberance of being too happy also can mess up thinking. Good and bad emotion can get our perceptions skewed and making big decisions on emotions can be really unwise, so going slow would be prudent.
