I think he means he is an Angel- of death.
He seems to think the solution for all females is to die. ( that would solve both your problems).
the others are right. I understand the closure, in the sense that you don't want him to hurt himself because of you, for the guilt would eat at you.
He does sound like he has a mixture of issues - and btw how did he get naked photos of you? Wtf were you thinking?
All the best though, But be aware this will not end well.
