Do you think men has competitive and violent nature?

as a man over the years this is something that i notice and can't deny, when i had first girlfriend there's many men tried to hit on my girl so i been in lots of fist fights, so i realized that there's no actual rules in love lives so i tried to hit on girls with bfs. i been on fist fights cuz of this too. not just love lif, work, friendship, our hobbies like everything has some competitive spirit against one another. thats why im now thinking its ok if two grown men with similar strenght/weight/height/age etc wanna fight like let them fight. violence is problem if its against a woman. i used to think its wrong the attack 3rd guy who the cheater cheating with but now i can understand it why its happening.
