A curious habit I noticed characters appear to have in Gremlins: Secrets of the Mogwai is that, while they are more than willing to kill gremlins, they do not kill mogwai spawn for whatever reason.
This usually happens whenever normal mogwai, namely Gizmo, get wet and then spawn new mogwai. Due to the curse placed on them by Fuxi, these mogwai are always more mischievous and most if not all of them can be quite malicious. Moreover, they are determined to eat after midnight which will allow them to transform into gremlins. Keeping these mogwai alive always seems to lead to them transforming into gremlins which later causes all sorts of havoc that the characters then have to deal with.
You would think that because of the obvious risks these mogwai spawn pose, it would be too dangerous to keep them alive and they should be killed. However, no character ever does this. While they may try to keep the mogwai spawn from eating after midnight, getting wet, and otherwise causing trouble, they still choose to keep them alive for some reason.
Why is it that characters are always willing to fight and/or kill gremlins, but do not do the same with new mogwai spawned from water?
