The devil himself is good when he is pleased.
One good head is better than a hundred strong hands
He that spares the bad injures the good
He teaches me to be good that does me good.
A good archer is not known by his arrows but his aim
When good people have a falling out, only one of them may be at fault at first; but if the strife continues long, usually both become guilty.
A man is not good or bad for one action.
A wise man turns chance into good fortune.
