If legally done...??? Sure it is legitimate hunting... No less so than those folks who shoot marmots in their natural habitat where they are doing no harm unlike the same critter near your home...
But to digress a little... That link to the injury and repair sequence is one I seen a long time ago... Someone (here I think) asked if my left arm injury was a rattle snake injury... They showed me this as my scars looked similar... I will add the similarity is uncanny...
Mine went thru a similar progression of many surgeries with a final skin grafting....
My arm got between roof and road/ground in an SUV rollover...
