Tell me, Boiled Brain. Have you actually read the Bible? That is, all of it? You'll find that in one book, YHWH is aggressive and murderous, and in the other, kind and loving.
Besides, in his eyes, and in the eyes of the ones who wrote the Torah, those women and children were not innocent; they were sinful.
"Evil" is a completely human concept. Among the gods, "good" and "evil" do not exist. In nature, "good" and "evil" do not exist. From evil good things can happen, and from good evil things can happen. Referring back to Lord of the Rings, after Gil-Galad overthrew Sauron and Isildur cut the Ring from His hand, a "good" thing, it resulted in Isildur claiming the Ring for his own, leading to his death, the loss of the Ring, its finding by Smeagol who becomes Gollum, and very fact that the Ring survives, which is an "evil" thing. On the other hand,
***SPOILER***
"evil" occurs when Frodo is finally ensnared by the Ring and claims it for himself, drawing Sauron's eye towards Mount Doom, and causing Gollum to bite Frodo's finger off. But from that, Gollum trips and falls into the pit of fire with the Ring, causing "good". Again, the "good" of the overthrow of Saruman by the Ents led to the Scouring of the Shire, an "evil" thing.
***END SPOILER***
There is no "good" or "evil" in the eyes of the gods. Try looking through their eyes sometimes. You think they got it easy just because they live forever and have some powers we don't have? The decisions they have to make for the survival of humanity are very hard, and sometimes for the good of the whole, sacrifices have to be made.
"Magic" still has to obey the laws of physics.
