What are the purpose of gargoyles what do they do ?

Architects started to include gargoyles in churches in times when most people couldn't write or read. Their function was to "say" that such monsters/ghosts/spirits/forces are dangerous outside and the only place one can be safe is the church itself. Eventually this form of communication worked as thanks to the gargoyles there were more and more believers among christians.

Answerstrophic and through-composed;

Personally, i think the games do because it's actually them controlling it. this might cause them to think it's okay to do it for real. as for animated movies i think they are mostly fine because they're animated. also, animation has come a long way causing animated movies to become more real but 30 years ago this wouldn't be as big of a problem as today.
