Hel is far, far, frombeing greedy. In my experiences with her, She is one of the most wisest of the Norse deities I have ever worked with. The wise are not greedy. I don't work with her often, but I know she is neither greedy or indifferent. She is death personified. The goddess of death. She knows what there is to know about life and death alike. In her hall, everyone gets their fair share. Whether they were rich or poor in life, it makes no matter to her. Everyone is equal under the eyes of death
Now, Snorri is a reliable source for the basic lore, but if you are wanting to go more in depth and really get under the skin of the norse pantheon, I reccomend Raven Kaldera, Galina Krasskova, and Amber Drake. Their UPGs are quite interesting. And when you form your own, it gets more interesting as you add your own to see what you can compare, contrast, and ultimately in the end, make your own personal conclusion and personal truth about the gods for yourself. I feel that it helps uncover more of the Pantheon and Norse spirituality itself, as well as it helps the Norse Pagan culture grow.
