User blog comment:Henshin1971/Should I put the category of 'good turn evil' & 'evil turn good'?/@comment-6532857-20150601043042

No.

A) The Toku Hub has that system.

B) categories exist to organize more than to provide information about a character. Thus we have allies, monsters, antagonists, ect, which systematically organize the articles. These categories add nothing to the current system.
