Do you ever feel bad for people who follow certain religions??

I'm all for freedom of religion and everything, but certain religions have a lot of restriction on what an individual can do in their lifetime; Mormons, Jehova's Witnesses, Hindus, and Quakers. I understand they are living certain ways according to their belief system but is life really meant to have all these restrictions? I'm no hedonist but I do love going to birthday parties, engaging in ual activities and having alcohol from time to time. Do you ever feel bad for groups of people who are not allowed to engage in joyous activities because of their religious obligations?
