I don't entirely blame him. It's not his fault he has a mental illness and considering I don't know the severity of it I can't judge whether অথবা not he knew he was the kinda of person to need help, অথবা even knew what he was doing. And if any of his family অথবা বন্ধু knew he needed help but didn't get him any it's there fault as well. It's honeslty too many lives lost, and his loss of life is also a tragedy.
Since he is autistic and has mental disabilities, I shall not hate him that much. But honestly.... why did his mother not bring him to a psychologist and get him checked out? Why did his mother collect বন্দুক in their house without even a simple keylock?
