BigGolem,
The shidduch column in the flatbush jewish journal discussed a girl seriously dating a guy with real anger issues. Anything would set off a tirade of cursing and anger.
If he has a bashert, there is a poor girl out there destined to marry him. She can look forward to a very tumultuous married life at best.
Every Jew has a portion in the world to come, but we must earn it through our mitzvos. Similarly, it is our responsibility to become worthy of our bashert. Someone who erupts in tirades of cursing and anger is not worthy of marriage. And, given what we learn in Pirkei Avos regarding violent anger and idol worship, his olam haba may be at risk as well.
