One thing I appreciated about Caprica is that everyone acknowledged that the copy was a copy. Zoe knew she was a copy. Daniel knew his daughter was dead, though his grief may have overwhelmed him to the point where he convinced himself otherwise. Adama's daughter knew something was wrong since she wasn't told she was an avatar. It's not like The Sixth Day where the bad guys didn't fear dying because they'd just be cloned -- even though they'd still be dead because the clones aren't them!
