Questions from a humble and ignorant catholic.

I am catholic from a small Texas town that only had one Jewish family in the county. Please forgive my ignorance. There is a temple down the street in my current city, and I have thought about going there and asking questions, but I do not know if I would be welcome. I try to respect all peoples and their cultures and beliefs. If I am wrong, please correct me. I am asking with reverence to gain understanding of a faith that I have no knowledge of but has played a pivotal role in the history of our World. Thank you.

1. I understand that Judaism doesn’t have a Christian sense of heaven. That basically the Righteous will be reunited with God? According to your beliefs do you have to be Jewish to reach this reunification state?

2.What happens to someone after they die who has been truly evil and intentionally hurt many people?
