I am planning to use a potentiometer as a variable resistor between arduino and a led to control the brightness of it, without putting a resistor between the led and arduino (I will use the middle pin and right pin of the pot in other words). Is it bad for arduino?

If you want to learn anything, you best first learn that you should buy a set of resistors. A lifetime supply is just a few dollars.
