Why did the Lord Buddha criticize natthikavādaṃ (moral nihilism)?

In SN 24.5, the Lord Buddha criticized the following doctrine called "natthikavādaṃ": > *There is no benefit in giving, sacrifice or offerings. There’s no fruit or result of good and bad deeds. There is not this world or the > other world. There are no duties to mother and father. No beings are > reborn spontaneously. And there’s no ascetic or brahmin who is well > attained and practiced, and who describes this world and the other > world after realizing it with their own insight.* > > *This person is made up of the four primary elements. When they die, the earth in their body merges and coalesces with the main mass of > earth. The water in their body merges and coalesces with the main mass > of water. The fire in their body merges and coalesces with the main > mass of fire. The air in their body merges and coalesces with the main > mass of air.* > > *The faculties are transferred to space. Four men with a bier carry away the corpse. Their footprints show the way to the cemetery. The > bones become bleached. Offerings dedicated to the gods end in ashes. > Giving is a doctrine of morons. When anyone affirms a positive > teaching (atthikavādaṃ) it’s just baseless, false nonsense. Both the > foolish and the astute are annihilated and destroyed when their body > breaks up and don’t exist after death.* According to SN 24.5, why did the Lord Buddha criticize natthikavādaṃ (the doctrine of disbelief)?
