I got a similar story, well minus the dead relative, but coincidence for sure I was in the crucible during house of wolves on on a horrific losing streak when a guy on the other team decided to tea bag me near the start of the match, normally I laugh at such childish things but it got to me this time. I began focusing on this guy, ensuring his death, even when I was out numbered by his teammates I would toss a trip mine back when they stuck to people at him to make sure he died, and I'd tea bag each chance I got to let him know why I was killing him. Eventually this happened so much that player raged quit allowing my team to win against the now outnumbered team and in the rewards section I got the sniper "low grade humility" with a flavor text of "I'm good at this" I fell of my couch laughing
