English: “Destruction is not His” — the damage is theirs, not His. The destruction is not His, but His children’s. “His children’s defect” — even though they are His children, the blemish is theirs. “A crooked and twisted generation” — a generation that has made its ways crooked and perverted its paths.
The midrash (and Targum) insists that the corruption belongs to the people, not to God; the dual adjectives underscore the thoroughness of the moral twisting.
