Now what about the issue of like being too drain happy in general?

There are consequences for every drain. Earth for example draining power from a tree (depending on the age and size) may cause the fruit to wither, or for it to no longer be able to produce fruit and in large power drains would kill the tree. Aedis are connected with their element and would feel shame and/or sorrow out of killing something they took power from.

For example, Iris would rather use power from her own life force and get a headache or nosebleed than to permanently harm something of the Earth.
