Go fish yourself.
Deepening redness can be a sign of healing and so can bumpiness. Here is some info on wound healing. Post more pictures if you can so we can see what his wound looks like. I'm not saying he doesn't have infection; just that he may not, and redness in a wound is not the difinitive sign of infection.
Also, I'm thinking Clove oil may not be the best method of euthansia in this case. Clove oil might cause pain due to exposed tissues. I'm thinking that it would burn or sting on contact with open wounds such as this.
While redness may not be a definitive sign of infection, the spread of the wound is. If it was getting any better it would at the very least stop getting bigger/deeper.
Whether clove oil will cause additional pain or not I believe is irrelevant. He must already be in excruciating pain, and while the clove oil might sting, it will knock him unconscious in a matter of seconds - at which point he will no longer be feeling pain. Researching other methods of euthanasia will only prolong the pain that he is already in for probably days.
I don't know about you, but if I had a painful wound like that I'd want the doctors to make it stop, even if that meant it would hurt more for a few seconds; rather than have the doctors sit around for days debating what to do, letting me suffer.
