priestley uses the inspector to educate the birling family about taking responsibility for their actions
- inspector's teachings critique the laissez-faire government in power in 1912
- "that doesn't make it any the less yours. she came to you for help" is what the inspector says to mrs birling when she says she believes it wasn't her responsibility to help eva because she wasn't the father of the child
- people should take responsibility regardless of their own involvement; failing to offer support is an act of cruelty
- those capable of giving help have a responsibility to do so
- eva's suicide is a symbol for the way the lower classes were blamed for their own suffering; "each of you helped to kill her"
- just because they didn't personally make eva drink the disinfectant, doesn't mean they are automatically innocent in her death
