God's Word is what it is, and whether stated in stark terms or more gently, does not diminish, change, nor "reduce" it.
God determines who/what He considers wicked, revealed in His Word.
The world's definition or benchmarks of "moral maturity" do not equal eternal salvation from sin and death. Only surrender to Jesus Christ equals eternal salvation.
Jesus taught specifics concerning hell. Some consider His teaching on hell a threat, some consider it a just warning. My consideration aligns with the latter.
