1) Frisk's SOUL shatters before SLR occurs - the vessel can use SLR, not the SOUL. Again, Flowey, a soulless being, uses SLR.

2) Asriel tells us that he ends the world (hyper goner)- and sans tells us in genocide that time stops. In the second phase of Asriel (Angel of Death), the physical realm is gone which is why we persist after death without re-fusing.

After SAVEing one monster friend of yours, Asriel doesn't attack. He just stares at you and smiles. His monster mix is able to resist the will of the human SOULs because there is no physical vessel at this time, similar to how Asriel resisted Chara.

3) He has a SOUL in TP - the monsters within him give him his own compassion, love and mercy back. That is how we are able to win the battle. We also reach into it to SAVE our monster friends. There's no physical vessel giving intent to Asriel during this phase, so he is able to resist harming the protagonist using the SOUL power that we restore by SAVEing our friends.
