What's the Limit?

We see with shock, the "cruelty" of the natural cathestrophe on mankind.
We see with pity, the "cruelty" of the animal abusers on animals.
But,
Can we see the "cruelty" we, a human being lash of another human being?
What is it that, do we call the limit to cease this "cruelty"?
Is it insanity? Or death?
The Lord and His Truth as set us free.
But what have we bound ourselves, or another human being to?

Man's traditions,
Man's cultures,
Man's wisdom,
Man's social acceptance,
Man's rules and regulations,
Fearof man,
Even man's own defined, or rather quoted, Bible verses.
Man... Man... Man...
When would you stop your "cruelty" on each other?
Didn't the Bible says: "The letter (legalism) kills, but the Spirit gives life."?

Do you really want to go on until you see insanity or death of th victim to call it "enough"?
What is the limit to the "cruelty" of mankind on another mankind?
When will man pause to think,
Which is more important:
Keeping the "good thing to do" or "keeping the life and sanity to live"?

P/S
Don't we have the trust on each other that
if one has the "life",
he/she would like,
would love,
would by their own inclination,
to keep the "good thing to do"?
