Why Is Davy Jones angry in the Pirates of the Carribbean Dead Man's Chest and At World's End?

Tia Dalma explains this in her big scene in DMC:

TD: "Him fell in love...(with) a woman as changing and harsh and untamable as de sea. Him never stopped loving her, but de pain it cause him was too much to live wid, but not enough to cause him to die. And so, him carve out him heart, lock it away in a chest, and hide de chest from de world. De key, he keep wid him at all times."

In less vague terms, he fell in upendo with Calypso, the sea goddess, who charged him with the duty of ferrying souls to the inayofuata world. Every ten years he could come on land for one siku to be with her, but ten years later, she was nowhere to be seen.

So can wewe see why he's a little pissed off?

Because, Jack Sparroe is ruining his life!
