So, as I understand, which I may be wrong about, using hemalurgy to kill a non-Allomancer/feruchemist takes some of their soul, which I would connect to investure. Using four investure spikes, you can make a Koloss, right? And it is described in the books that you slowly lose humanity as you gain more spikes as you become a Koloss. Does that mean that an aluminum compounder would just end up making you less human?
