Quote #4

PROSPERO
Thou most lying slave,
Whom stripes may move, not kindness, I have used
   thee,
Filth as thou art, with human care, and lodged
   thee
In mine own cell, till thou didst seek to violate
The honor of my child. (1.2.412-418)

For Prospero, some things are beyond forgiveness.  This is one of them.

Quote #5

SEBASTIAN
Sir, you may thank yourself for this great loss, 
That would not bless our Europe with your daughter,
But rather lose her to an African,
Where she at least is banished from your eye,
Who hath cause to wet the grief on 't. (2.1.131-135)

Sebastian has no pity, really. It's no wonder he could move so easily from mercilessness to treachery.

Quote #6

CALIBAN
Beat him enough. After a little time
I'll beat him too. (3.2.92-93)

Caliban, having been shown very little mercy, has no capacity to show mercy to others, and in fact takes delight in others' suffering. Is this a defect of his character, or the result of a vicious circle of mercilessness?
