What's the main difference between the "curse" and "swear?"

Within the context of saying profanities, "cursing" and "swearing" mean the same thing! Otherwise, the difference is that to "curse" is when you say something against someone - to damn or punish them. To "swear" can mean to make a promise or oath. Ex: Stop cursing at the computer game, Tim! = Stop swearing at the computer game, Tim! Ex: I curse the person who stole from me. Ex: I swear, I'll never do it again.
