What should I do with this injured opossum on my patio?

I don’t know if it is sick or injured, but it is still alive. My husband is at work and told me to kill it. I told him I just couldn’t do it and what does he say? “What if it was a zombie apocalypse!?”

Do I get the courage to kill it? Do I try to scoot it out to the woods behind our house? Do I wait for my husband to get home and be called a wuss for the rest of the weekend? What would you do?
