During the last part of DH, Snape was pleading with Voldemort to allow him to bring Harry to Voldemort. I assumed that he was going to give Harry a chance to disarm him and take the Elder Wand from him. In that case, would he ever have owned up that he'd killed Dumbledore on Dumbledore's orders, and that he was always working for the side of the "good", so to speak? I mean, I really can't see Snape confessing to Harry any of the things that Harry came to know from the memory. Or, would he have confessed?

Snape needed to tell Harry about the fact that part of the Horcrux was in him, but I doubt that Harry would ever have spoken to Snape, let alone believed anything Snape said. So, was he thinking of giving the memories to Harry anyway, or was that some thing he did when he was dying, because he couldn't say the things?

Would Snape ever have told Harry that he loved him? I don't see him doing that. In fact, I don't think he could bear Harry knowing the fact (by whatever means, such as the memory) while he was alive. Or, had he changed and was thinking of showing Harry he loved him?
Your opinions, please.

In my own opinion, I don't believe that wanting to confess was his purpose in "pleading". Also, I'm sure that Snape did not know about the Horcrux (but that they had a connection), only Dumbledore did. Lastly, Snape did not love Harry. At all. Not even a little bit. He was happy for Harry to die to get what he wanted. He loved Lily, but that's where it ended.

he would have given him the memories, then he would have ran away.
