You care about your family, which at least shows that you are still a kind person. It's her fault that that woman hurt you, but you always use her fault to punish and torture yourself ... it's not worth it. If you kill her, your suffering will not disappear, but will be transferred to others, to those you love and love most. Doesn't this kind of injury mean that it is about to expand? I believe you don't want to see this day. Please think about it. Why not let this damage stop here? This is her fault. Why do you have to bear such a painful price? Even let your relatives continue to bear it for you. Your brother has a bright future now. Please live well. Your brother wants you to live and watch his tomorrow get better and better. He wants you to share his happiness and beauty. Do you believe in karma? I believe. It's only a matter of time before those who deserve it escape.
