A Scout is Kind.
A Scout knows there is strength in being gentle. He treats others as he wants to be treated. Without good reason, he does not harm or kill any living thing.
A Few Bible Verses that seemed relevant to the points being made in this part of the scout law:
Proverbs 15:1 - A soft answer turns away wrath, but a harsh word stirs up anger.
Luke 6:31 - And as you wish that others would do to you, do so to them.
Proverbs 12:10 - A righteous man has regard for the life of his beast, but the mercy of the wicked is cruel.
