Way it was shown all the pirates under his wings and his allies were ''good'' and he made a living by protecting islands.
he literally had Karma, the same guy that tried to kidnap and sell Toki to slavery, as a subordinate.
Squardo stabbed him in the heart first chance he got. That doesn't look good for wb or roger cause roger murdered Squardo's whole crew.
Then there's teach. Wb would have had no problem with him if bb just didn't kill Thatch.
We simply don't know enough about his allies to call them "good".
Also, one of the ways wbp made money was by turning in pirates they defeated to the wg and collecting their bounties. So they literally sold their fellow pirates into lifelong torture for money. That doesn't seem very good to me.
