Personally, yes.
Without islam, I'd not care to mistreat who is harming me wheather he is Muslim or not.
But Islam encourge me to forgive the unbeliever if they harm me.
me, therefore I follow-step my shining example I mean my prophets like Ibrahiam who set an example of dutful person to his parents I mean His non-Muslim (Believer)father.
Or My last prophet Mohammad who forgive to kuffar people who totrued him when the upper hand was with the Prophet.
Allaah says concerning this (interpretation of the meaning):
“And by the Mercy of Allaah, you dealt with them gently. And had you been severe and harsh‑hearted, they would have broken away from about you; so pass over (their faults), and ask (Allaah’s) forgiveness for them; and consult them in the affairs. Then when you have taken a decision, put your trust in Allaah, certainly, Allaah loves those who put their trust (in Him)”
[Aal ‘Imraan 3:159]
etc.. etc..
Without Islam, I'd not care to protect other people rather i'd not care to be rude and bully.
But because islam make insulting people, laughing at them or looking them down a henious sin, i fear god to indulge in such a sin for sake of god in order to please on me.
I'll give you an example, When a man insulted his brother (in Islam) for having a black mother, the Prophet (peace and blessings of Allaah be upon him) said to him, “You are a man who still has jaahiliyyah (ignorance) in him.” Abu Dharr (may Allaah be pleased with him) said: “There was an argument between me and one of my brothers whose mother was non-Arab. I insulted him about his mother, and he complained about me to the Prophet (peace and blessings of Allaah be upon him). I met the Prophet (peace and blessings of Allaah be upon him) and he said, “O Abu Dharr, you are a man who still has jaahiliyyah (ignorance) in him.” (Reported by al-Bukhaari and Muslim; this version narrated by Muslim, 3139).
Without Islam, I might steal (If i found a chance to do)because no body cares nor suited me.
But, because Islam taugh us that Blood-money and expiation must be paid if one unintentionally kills a "disbeliever" (Accident by car for instance )who is protected by sharee’ah, i scared to just attempt to commit such a crime.
Btw, If a Muslim deliberately murdered non-muslim The Prophet said, "Whoever killed a person having a treaty with the Muslims shall not smell the smell of Paradise though its smell is perceived from a distance of forty years."
Also,Since the upper hand was with the Muslims, the Prophet strictly warned against any maltreatment of people of other faiths. He said:
“Beware! Whoever is cruel and hard on a non-Muslim minority, or curtails their rights, or burdens them with more than they can bear, or takes anything from them against their free will; I (Prophet Muhammad) will complain against the person on the Day of Judgment.” (Abu Dawud)
That's why I need islam to abstian me from commiting any corruptian.
I more intoxcated for helping you to understand the reason.
