The Irish werewolf is different from the Teutonic or European werewolf, as it is really not a "monster" at all. Unlike its continental cousins, this shapeshifter is the guardian and protector of children, wounded men and lost persons. According to some ancient sources, the Irish werewolves were even recruited by kings in time of war.
Wolves are far from viscious, in fact you're more likely to get attack by a domesticated dog. I watched a programme on telly once, this bunch of guys were studying a wolf pack, one night they woke up to find the pack had discovered their camp and were in amongst them, in their tents nosing around. But didn't attack.
A little later when the Alpha female gave birth, the trust that had built up was so strong she would let the guys into her den with the cubs. And yes, they were wild wolves.
