Depends. If I lived in burgerland, it's probably better to just call the police. Risk doesn't outweigh the reward. However, where I live the chance of someone owning a firearm is low. If he's beaten by some niggers/moroccans on the other hand, then it'd be dangerous too and I'd call the police as well, because they all carry knives here, especially young zoomers nowadays. They even started banning them in high schools here because it got so bad JFL.
However, if it's some native homos, I'd observe and gauge their fighting ability for the first few seconds. If I notice they're inexperienced fighters (very easily to ascertain by the way they throw punches/kicks) I would jump in and crush them - no mercy (of course all IN A VIDEO GAME XD!).
Yesterday I went boxing with a novice friend of mine. He's about 190, I'm roughly ~171, 173-175 with shoes on, and still managed to beat the fuck the out of him despite going only 50% of my max, which shows that height is not important in fights. It so happened that three roughly ~160cm manlets passed by and were mocking him. They shouted something like "ThAts NoT reAl sParRIng dUde!". If they came up to escalate, I would
trample them. I even jokely in a friendly way said, "Yo, guys you wanna give it a try with me for fun to see if you can last?

Of course, they went about their day like the pussies they are and walked away.
When I still was doing MMA I fought and grappled with arguably the best fighters in the Netherlands (they won many national tournaments). Our trainers were so confident and saw potential in me that they wanted me to participate in tournaments as well, however uni and other shit came in the way.
All hypothethicals Of course and in A Video Game.
