I think to deny responsibility, the notion of doing the right thing is highly subjective. If I shoot your dog and deny responsibility that makes me a liar as well. If I shoot your dog just because I do not like dogs in the first place and claim it was the “right thing to do”, few would agree with my methodology, but…if the dog was vicious and had brutally ripped the face of of an innocent child it could be claimed that shooting said dog was the right thing to do.
