Guys, would you feel guilty in this situation?

This happened to a guy I knew in school long ago. I still think about it.

Suppose you once talked to this nice and sweet girl you met on the internet for a while and while she caught deep feelings, you lost interest in her and started ignoring her. Then months later she reaches out to you again and confesses her feelings for you and you are bored so you go along with it for a while and then loose interest completely and ghost her again.
Then her sister reaches out to you one day begging you to talk to her once as she is really depressed. You are really fed up and don't contact her. She messages you one day asking if you can just be her friend but you don't feel like doing it. You find out after some time she committed suicide because of you ignoring her.
