Do you think that taxidermy is wrong?

I just saw this bizarre listing on Craigslist: https://seattle.craigslist.org/see/for/d/silverdale-taxidermy-squirrel-duck/7254325773.html

Is that sick or what?

When I was in my 20’s I got into taxidermy. It was a challenging hobby that made me money mounting deer heads, birds and novelty items. But one day I walked into the garage (where I did my taxidermy work) and looked around at all the birds, squirrels and even a stuffed turtle and a Black Bear head. Suddenly I was grossed out and quickly got rid of everything.

It seems so wrong to me to put dead animals on display.

What do you think?
