I wanna create a spell that damages nearby enemies based on healing aura spell and I tried to do it but I did not succeed.Where do you think my problem is?

Try adding "organic" to the targets allowed or remove debris to see if that changes anything

No, problem is not targets, It's works but only affect wounded units.
I think this is for the base ability healing ward. How to solve it?

Use permanent immolation as a base ability instead. Negative regeneration abilities don’t give kill credit or gold when they kill units so they are not the preferred solution.

To add to what @Pyrogasm wrote, the reason why the negative regeneration isn't working is because said enemy units aren't actually damaged until their HP drops below max. The game isn't built to handle negative regeneration, so what it's doing is detecting if a unit needs to be regenerated. If it's at Max HP, even if the regeneration is negative, WarCraft 3 doesn't think that it's supposed to be applying regeneration.
