1. If I didn’t know which neighbor, I would judge all of them and hate them forever.
Well, they all hate you forever already because you disturbed them with the shrieking, so they probably don’t care what you think at this point.
2. Different people have different definitions of “shrieking”. It is normal behavior for babies, for example, but I never call the cops on my neighbor who has three screaming babies.
Most people are smart enough to distinguish benign sounds from frightening ones, despite the fact that language can be inexact. If someone says, “I ran inside and locked the door because I heard a growl”, I’m not going to retort, “well maybe it was your stomach growling!” You’re alive today because your ancestors somehow avoided getting eaten by lions.
3. He can just ask the neighbor if he is being abused.
You’d first have to determine which neighbor made the shrieks (assuming they survived).
