The first link I can comment on. I do not know enough about eschatology to comment on the second link.
First, love is a choice. Robots do not love. Sin is the price of love. God thinks the benefits outweigh the cost. Next, God has answers to men's powerlessness over sinful desires. Read the book "The Normal Christian Life" by Watchmen Nee. It is a classic.
Lastly, I have not read Plantinga in a long while (I gave you the link). If memory serves though one of the things Plantinga says is that evil creates good that otherwise would not exist (courage, patience, etc).
I hope these resources help.
Sincerely,
Ken
