The life of a goalkeeper is a difficult one. If any other player on the field makes a mistake, they are usually forgiven pretty quickly. Goalkeepers, on the other hand, are expected to be perfect. Even the smallest mistake could ruin a keeper's entire career. Robert Green is a perfect example of this.
I believe goalkeepers do deserve a little more slack during games. That being said, some mistakes aren't really forgivable, and, with the way they pan out, can end up being pretty ridiculous.
Take Vedran Janjetovic for example. Janjetovic is the goalkeeper for Western Sydney Wanderers in the A-League. Back in January, the Wanderers were up 2-1 against Brisbane Roar FC.
