"I feel sorry for you."

How would a Russian say, "I feel sorry for you," in a derisive context?

This phrase is often used when commenting to somebody who has behaved in a deplorable manner.  

I do not mean, "I feel sorry for you" in the context of, for instance, your grandmother just died.

I'm wondering if it would be, Мне жаль тебя.

Clarification

Hello everyone! =D

A friend and I have been studying at the Institute of Russian Studies and Culture in SPB. We were put into a class that had been going on for a while and obviously there are things that we've had to just learn on the fly. The professors are, thankfully, very patient and realize that certain things we haven't learnt.

However, we're just looking for some clarification on some grammatical nuances that we've briefly covered in class. Of course, the explanation to these grammar rules are in Russian and sometimes you don't understand the complete meaning of when and how to use it.
