Are we all humane? Do we have humanity? NO.
We are all so selfish, but how can we live like we aren't, when we live in a selfish world?
That is where we make the mistake - if you choose to change, life would be so much easier- then we wouldn't have to cross dangerous territories, then we would be safe.

She has to cross unsafe roads and walk on dangerous territory to save herself.
