Envy is one of the capital sins. Like the Monsignor said — people are willing to kill to get what they want.
> “... people are willing to kill to get what they want.’
Or they are willing to work for it. I don’t know about who deems what words go on a list of ‘capital sins’ but I am sure if I am in prayer to Our Lord and I express how envious I am that my neighbor is doing so well and to please bless me with the strength and wisdom to earn what I need so that I can be as prosperous as my neighbor, I do not expect to be condemned.
The Lord may instruct me to be happy for my neighbor’s blessing and that such blessings or other blessings await me. But to be condemned for wanting, seeking and working for something better is no sin in my mind.
To me, ‘jealousy’ means to want to take from my neighbor to have as my own.
Whereas, ‘envy’ means to want to earn that which is similar to what my neighbor has gained.
“I am so envious of your success, I want to be like you”.
“I am jealous of your success and will seek to take it from you for my own.”
That's not envy, though. Envy is being willing to kill so that someone else doesn't have what you want, even if you can't get it.
