A sin compounded

IF you've broken one command you've broken them all.
That is true, but only because ALL SIN STEMS from idolatry.  You would not steal if you were seeking God.  You would not murder if you were seeking God.  You would not fornicate if you were seeking God.  You would not DO ANYTHING that God forbids if you were seeking God.

If I stole a penny from your bank acct, you'd be outraged.  But would you be outraged because I'm not seeking God with my fullest strength or would you be outraged because of the potential for more money to be stolen?
If I stole 3/4 of your income & current 401k value, you'd be having difficulty doing things you know you need to and should be doing.  Unless of course you have 1 billion+ dollars collectively......  Money is important to God, it's important to people, thus all the more important to God, although God does not talk at great lengths about the value of money because we as functional human beings KNOW TOO WELL the value of money.  We OVERvalue money.  We do not need God to tell us how wonderful money is.  We DO need God to tell us that HUMAN LIFE is precious!  We do not value human life as much as we should.  We do not value others' existence as much as we should.  We should not be focusing on what we do not have.  Whatever we have by consequence of our righteous deeds or directly by the provisions of God should be enough.  Thus God does not condone taking someone else's penny or dime or nickel.  God may more easily forgive you for taking a penny vs. taking a million dollars, but the taking of a million dollars is not only a sin against God but a sin against people.  God does not exist independant of people.  He CAN exist independent of people, but He has chosen not to.  He is interested in us and he wants us to thrive in our lives.  You would repent of your theft of one penny by giving it back to the person you stole it from and by asking God to forgive your sins knowing your heart has drifted farther from Him than He is OK with.  But apologizing to the person you stole it from should not be made because of the wrong you did.  It should be made because of the increased distance you've created in the heart of one who already needs to get closer to God.  Yes, it stems from a sin, which in and of itself can be construed as hypocrisy, but the apology should not be some drawn out Lifetime movie of the week seminar.  It should however be sincere, and clear and believable.  The same is true of a Christian seeking to turn a bank robber's heart toward God.  Even if the bank robber did not kill anybody, or had good intent, nobody likes banks being robbed.  Bank tellers don't like being threatened.  Customers SHOULD NOT like watching bank tellers be threatened.  You may hate taxation and the greed that banks exude or some combination in whatever measure, but the people effected most in a bank robbery are the low level employees and the customers/consumers.
Beyond that, God does not limit what He forgives you for.  He can embrace a sincere willingness to repent from ANY sin, including murder.  Some sins are more difficult to deal with for the average person.  Getting angry is not forbidden amongst Christains.  Letting it linger longer than necessary IS forbidden.  Letting it lead to murder IS forbidden.  You are not repenting from your sins if you persist in anger.  A person who is homeless and steals a Snickers bar is not necessarily unrepentant.  They have some work to be done in their relationship with God, but I don't think they are any more evil than 99.999% of churchgoers in any or all denominations.  I don't think a person who masturbates because they aren't married is necessarily any more damned than 99.999% of churchgoers in any denomination in whatever country. 
I do believe I've been going backward in my walk with God the last few or so weeks.  I've been stagnant, somewhat.  I do need to drop myself and submit to God.  I don't know how to do that.  I need to engage with His Word more in the hopes that He will provide a means to do that within my heart and mind.

 He is Lord of all, King of Kings.  He does not condone our beings.  But He does understand and accept the reality of our limitations and has demonstrated a willingness to connect with us by sacrificing His Heart for Ours.  He demonstrated that publicly by showering His Wrath on his manifestation on Earth and privately by dwelling in our hearts and keeping a light lit for our journey in this world.
