demons are corrupted souls so can't theorectically be killed.

i'd like to think they go to purgatory, although people will disagree with me because its a place for monsters not demons.

i'd like them to bring Meg back somehow (me being a huge megstiel shipper), so unless a new season offers a new dimension for demons, then im going with purgatory. especially as now cas is human so he can go save meg and get through the portal so it will be perfect and they can buy pet unicorns and sit on rainbow clouds.
