From the original description "detriment of the larger institution" might be inappropriate. After all he gave more than 25 other people a chance to publish.

And if we assume that some of those experiment involved master students then for a few of them that was their first publication. It look like he was kind of a unmoral presence from many point of view, but you cannot ignore that he probably helped many people get more experience.

Again I am not claiming that what he did was right, but it is neither necessarily a detriment to science.
