executing them will be an appropriate expression of God’s compassion for the righteous, whom he will preserve.
Charming little comment right there.
Plus "appropriate" is one of their favourite words. They consider themselves the world experts on what is "appropriate", from when it's "appropriate" to ignore family members to when is an "appropriate" time for God to act. I'd like to do a search of WT literature for "appropriate" occurrences. They are especially good at telling God what is appropriate.
How would we ever know what is appropriate without Watchtower to tell us?
