It's kind to end the suffering of a sick pet.
Daniel's cat, Mr.Paws, has been ill for two months with no signs of getting better.
Daniel wants to end Mr.Paws' pain.
Daniel realizes he can do no more for Mr.Paws and takes him to the vet to be euthanized.
Daniel gives Mr.Paws medicine every day even though it doesn't help.
Mr.Paws no longer has to endure any pain.
Daniel's actions only extend Mr.Paws' suffering.
