I think Jesus is all very well, but there are cases of absolutely unpardonable wickedness which merit no 'mercy' whatsoever.

For example, a few days ago, a man threw concentrated acid into the face of a three year-old child in a shop in Worcester. The infant screamed in agony and his face and arm were terribly burned. It's thought it was a 'family feud'. Eye for an eye? I'd have torn his head off!

Regarding the rich landowners, there are many National Trust properties in Norfolk which we enjoy visiting. But grand and imposing as they are, the quarters for their servants were evidently the most miserable, mean and meagre areas of the house. Tiny attic rooms (freezing in winter and boiling in summer) with hard beds and so on, and the service rooms (kitchens, laundry etc) down in the basement, damp and unhealthy.

The owners obviously had no interest or fellow-feeling in providing some comfort and pleasant surroundings for their minions. And the folk in the surrounding villages had lives of deprivation and poverty.
It's certain that the rich folk's sense of entitlement overrode any 'Christian' tenets of compassion.

'The rich man in his castle
The poor man at his gate,
He made them high or lowly
And ordered their estate.'

In other words, they had a God-given right to their wealth.

Interesting that this verse of 'All Things Bright And Beautiful' was surreptitiously dropped at a later date!
