So, even without a shred of conditioning, skill or talent (which is about 90% of the population), the simple disregard for the safety of self or opponent, and the willingness to press forward, will carry most contests, until a significantly greater level of condition, skill, talent and/or pure size is encountered. Ergo, the myth of unbeatable anger.
Absent the presence of skill, anger or determination could be the difference. Against skill, however, I'd wager it is a heavy drag on the likelihood of success.

I love to get agressive but I don't like getting angry! when you're angry you tend to tense up and get more tired without even realize it
You can be turbocharged without being angry
