'I will not let you fall into madness.'
'Give me this one chance, to save you from the darkness.'
Serena was a goddess who lost everything even after trying to rebuild herself several times. The gods above easily destroyed and took everything away from her.

—How can I trust you when you have already done that?
—I waited so long until you could withstand me, and then you chose another!
