Father kills his 16-year-old daughter because of his relationship with a stranger/ Defendant: I have no regrets, I have no guilt

The murderer's father:
After I separated from my wife, I wanted the children to live with me, but their mother wouldn't let me. He was a drug dealer and was in contact with unjustified people, and I was worried about my children. A year and a half ago, a man named Asghar, who was friends with my ex-wife, harassed me.
He tried to scare me by shooting shots and setting fire to my house. It was at that time that I thought I would have to buy a gun to save my life, and I bought a Colt for 70 million Tomans. A few days later, the man called me and claimed that he had a secret relationship with my daughter.
I asked my ex-wife several times not to ruin our daughter's life, but she didn't pay attention to what I was saying until I checked my daughter's phone messages and realized that she was having an affair with Asghar and I decided to kill her. Even now, I have no regrets and no guilt, I should have killed my daughter."
