***The Mark 10 verse you sighted JM has said is a demonstration of the compassion aspect of universal love.***
Yes, but the inclusion of that word in the context of Mark 10 has special significance. Jesus is specifically recorded as "loving" 5 people, Martha, Mary, Lazarus, the "Disciple" and this young man. And though we know he certainly loved many more, this just serves to highlight the uniqueness of the use of this word in this context.
I believe to equate it with some expression of "universal love" is to miss the significance of it's inclusion in Mark 10.
Do you believe that God loves "the world" in the same way as the five people you have mentioned? How the same or how different?
