Anger is a dangerous emotion, it can make the smartest people do the dumbest things. In a fight however, anger is ten time more dangerous.
No person should ever make any sort of decision if he's angry, even more so when fighting. In a fight, anger can cloud the judgment, ruin the awareness, and destroy common sense. All the trades that are crucial for winning a fight, and the lack of them can get a person hurt or worse.
In a fight, you need to be aggressive, not angry. There's a world of difference. Any idiot can go crazy from anger, that by the way is considered to be temporary insanity. Sure, it makes anyone dangerous, to himself and others. But not nearly as dangerous as a professorial, who can be 100% aggressive, and still stay in control of himself at all times. No emotions, purely the business of fighting.
What you need in a fight is called control aggression. If you're able to do that, then you'll become a dangerous person when need be.
Through proper training, aggression is a tool you could learn how to control, and switch on and off when needed. Without losing common sense and sanity.
Take care, Train smart
This statement is somewhat true. I say somewhat because not everyone has an aggressive streak. Some people aren’t wired that way until they become angry. A lot of women are mild mannered until their child is messed with then the Mamma bear comes out and it’s full on rage. Rage is what’s dangerous that’s the uncontrollable I’m going to rip your head off anger. I’m going to go geek mode let’s look at Hulk anger and aggression but as Bruce banner nothing. Mace Windo his back story is he’s gotta as close to the dark side as one could be without given in so angry but not aggressive. Aggression doesn’t equal anger and anger doesn’t equal aggressive. Also being angry doesn’t make everyone stupid. You can be angry but control it and tap into the dark side and use it if need be. Some people can be angry about something but not aggressive enough to do anything about it. Also some people can be an aggressive person but not angry about what their doing. A quote from Mark “Oz” Geist I don’t have to hate you to kill you. So stay calm think clear and be aggressive.
