depends on the locality and the situation. Virtuovice is allowed by law to hunt a substantial number of dear in his locality in japan because the hunting program is meant to keep the deer population in check. Leaving 90% of the carcass in the woods isn't inherently wasteful, except in the destruction of built complexity, because the carcass will be used by local wolves, scavangers, and eventually plant life.
Thats not to say that it should be done by everyone, I just mean to point out that there are situations where it's both 'not a crime' and not the worst natural order to take place. Deer wreak havoc on local biodiversity, cutting plant variety down to a minimum of inedible varieties, both killing the deer and allowing them to multiply beyond the local area's capacity is destructive. It's more a pick your poison situation than black and white moral scenario.
I've always loved the look of japanese knives in that style. Gorgeous. I've never owned or felt the desire to put money into one, but visually they are awesome.
