It helps things, I suppose.

And you can't expect to collect a lot of poor wretches together and manufacture first-class Magdalens out of ninety-nine per cent of them, because you're the one that needs no repentance, can you?
I forget whether the Bible says it was ninety-nine who did or ninety-nine who didn't, but you'll understand my drift, I daresay.

It's logic, if it isn't Scripture.

All right.

As long as you can stop the evil, without doing wrong yourself, you're bringing about a good result.
