Was it alright to kick my uncle in the nuts?

Hi, I'm Jade, a 16 year old girl. I have an uncle, and he had a very, very nice life and was married, when things went downhill, and he was divorced by his wife. That was seven years ago, and after the divorce his life started getting ruined and he started to drink way too much. It's kinda sad. Then last year, my family was staying in New York for a visit. One night, we went to my uncle's apartment to say hello and have dinner since he lives in NY. Sometime into the dinner, no one noticed my uncle, but he'd been drinking during dinner and he raced out of his apartment without anyone noticing but me. I knew he could, and probably was drunk so I followed him wherever he was going without him noticing. I took the elevator cuz I saw him take the stairs and didn't want him to see me, and when we got down at about the same time, he raced across the street to this bar and i followed him. There at the bar, I saw him saying to this woman, "Hey babe. Whatcha up to?" She said "Get away sicko!" And he said "Don't be like that" And I knew he could be doing something bad so I kicked him in his dicebags from behind as hard as I could and got a perfect strike. He fell down like a rock and started screaming, yelling, and shrilling because I hit him right on the hardest part of my shoe. And he was rolling around and sweating and looked like he was gonna vomit. After that I apologized for my uncle's rude behavior to her and she said it was no problem and then the woman walked up to my uncle who was on the ground, taunted him for hitting on her before, and kicked him with the tip of her shoe in the groin. After that I dragged him up back to the apartment, and by that I mean I helped him get back up. Do u think this was the exact proper course of action to take? I was just thinking for the best.
