"I have to sin because those non-Christians might sin" is an interesting chain of thought.

Religion is about many things, and a major theme is depriving yourself to demonstrate your faith. Refrain from sin, pray for forgiveness and repent your mistakes. Live as a good example, give aid and charity to others. These are all commands in the Bible.

Concern yourself with your own sins, not those of others. Do all this and you will be rewarded in heaven.

Wonder what Jesus would have to say about your thoughts here - that you have to break the commandments of your God because if you don't, someone following a different god might break them first. It doesn't sound very Christ-like to me.
