You mean like supporting Germany and Japan in 1944-1945? German and Japanese civilians were dying in the thousands. How could it be wrong to support imperial japan and nazi germany by opposing the allies?
When it comes to strategic bombing, honestly, yes.
It boggles my mind that militaries keep attempting despite decades of experience showing that damn near every single time it's been attempted, it's been an abject failure in its aims and very often entirely counterproductive.
