The person with the broken soul--how different is s/he? What broke him/her?

So what is your opinion then on the exploitable weakness that Sam and/or Dean would intentionally let the Last to merge with them so they could control it? Because it could be a cheap solution if not handled properly.

You mentioned the acts are like seals. So does this imply the Last is intentionally making those changes? And to what end? Or was it just influenced by whoever it merged with so such changes would be made?
