Meaning that even in terms of SAVING, having DT outside of our SOUL is the best option.

So putting more INTO the SOUL would be a BAD thing.

Usually. It would help making the SOUL REFUSE. But one would probably have to actively focus on that.

So unless you really don't want to die (For example, die too many times and you're forgotten from this world and Asriel takes control over the timeline), it's better to keep it outside of your SOUL, so you can reload when it shatters.

This might just be why we can't refuse in battles other than Asriel's.
