Not a mercy kill

My readers, life is not easy. And in a world of unreasonable need for perfection, some people may decide on suicide. What I have a hard time grasping is how a woman can kill her child just because she wishes to die. A doctor in New York shot a child before killing herself. What reason could that child have had not ot want to live my readers? Having a child is a responsibility, some say it’s a reason to live. I don’t know but my readers, I know people can chose suicide of they wanna. Nobody can stop them. What is evil is killing someone who deserves their very own life to achieve it.
