He put her in there so he could save her. So he could set her soul free...
"My daughter, if you can hear me, I knew you would return as well. It's in your nature to protect the innocent. I'm sorry that on that day, the day you were shut out and left to die, no one was there to lift you up into their arms the way you lifted others into yours. And then, what became of you.I should have known you wouldn't be content to disappear, not my daughter. I couldn't save you then, so; let me save you now. It's time to rest. For you, and for those you have carried in your arms." Im sorry...that sounds like he loves her. A lot.
