The good thing refers to the liberty to eat meat or to do anything amoral. People could legitimately speak of it as evil if it resulted in the fall of a brother. [source][source][source]
Context Summary
Romans 14:13-23 - Yielding Rights For Others' Sake
We must be careful of one another's faith. Unkind criticism or ridicule, or the strong pressure of our arguments and reasons may impede the divine life in weaker natures by leading them to act in defiance of their own conscientious convictions. We must not flaunt our greater liberty or urge men to act against their conscience. We may, of course, temperately and lovingly explain why we are not held by minute scruples. We may show, as Paul did repeatedly, that Christ has called us to liberty; but we must not attempt the regulation of one another's conduct from without. The sanctuary of the soul must be left un-invaded. The Spirit alone may speak His oracles in the shrine.
Leave each disciple to his own Master, each plant to the Gardener, each child to the divine Fatherhood. In many things you may grant yourself a wider liberty than others allow themselves; but it must be used wisely, and you must refuse to avail yourself of it whenever those around you may be positively imperiled. We need not mind the censorious criticism of the Pharisee, but like the Good Shepherd with His flock, we must accommodate our pace to that of the lambs, Isaiah 40:11. [source]
