I'd ask myself.....CAN he kill it?

If you think you can get him in there, clean, and either:

1. give him a LEGITIMATE opportunity to take this deer.......I'd take him in.
2. If you think your intrusion wouldn't mess it up, for YOU, then I'd take him in there.

If I thought he wasn't capable of going in there clean and getting the job done.....I honestly wouldn't risk it.

You asked.
