1) It doesn't say directly. But there is circumstantial evidence.

2) Or the usual children's curiosity. Or even a thousand other reasons.

3) Only the gun is a real weapon.

4) "They feared the monsters ability to absorb human souls".  How could humans know about the ability of the monsters? It is obvious that the monsters have shown it. Monsters that have absorbed human souls could be a cause for fear and war.

5) Monster with a dead child in her arms. This is a very hard scene.

Monsters killed Frisk constantly. Not only the Royal Guards. Even cute Tsunderplane will kill Frisk. This is a consequence of the policy of Asgore. He not only killed the children. He teaching other monsters that kill human children is normal.
