Revisionist history - are you David Irving by any chance?
Absolutely not!
The Dams raid, was seen as necessary and it's reasoning accepted at the time by those who sanctioned the effort. That included the full impact of hitting that target - as apart from the effect on industrial production, the immediate collateral damage would be overwhelmingly civilian. Non of the targets were in fact military, and that in my view places the raid alongside those of the area bombing campaign, and as you point out - we don't celebrate that.
Which leads me to my thoughts in the original post.
