♥ Serious Question for Christians: If you knew someone went to hell because of you would you kill yourself?

The truth is that we can't and don't save anyone, as you know, God saves them. Our job is to present the message. So if a person ends up unsaved it is really in God's hands not ours. In the case you mentioned, even if things were resolved that is still no guarantee that they would have become a Christian. And, even f the conflict remained God could have raised up someone else to share their faith with them. So I would press on and trust in the Lord to work out all the details.
