I hope it doesn’t. How could you be bothered that everyone else will receive the same benefit that you are going to receive?
If it does bother you, you might consider what that says about your character. It’s not as if you’ve earned the way to heaven. Jesus Christ paid the price for you. You wouldn’t have a chance without Him and neither would I.
Just because everyone is going to heaven doesn’t mean that there’s no such thing as sin, or judgment, or consequences for behavior. On the contrary, all these things are true also. We receive judgment for our sins in this life and in the next life for those that don’t get judged in this one. God will be fair. But He is not going to sentence anyone to an eternity without Him. Would you want Him to? I hope not.
If you’re happy that everyone is going to heaven, be happy and repent of your sins. If you’re sad that everyone is going to heaven, repent of your sins – including the sin of wishing such evil on your brothers and sisters.
