My co-authors and I are preparing to submit a major project manuscript. Unfortunately, we have just learned that one of the persons involved in the project has committed major scientific ethical violations related to the project, but not directly impacting this paper.
The scale of the ethical violation is quite large (think: non-consensual and dangerous medical experiments) and is directly connected to their work on the project. It does not, however, affect the validity of this manuscript or their contributions to it in any way.
Many of the co-authors, however, no longer want to be associated with this person in any way, and are likely to withdraw their names from the manuscript if this person remains an author.
Would it be reasonable to remove this person from authorship based on their ethical violation, essentially as a form of community shunning?
