Ever steal something? Piece of candy? Paperclip or a pen from work? That's taking something that doesn't belong to you. You, then, are a thief. Have you ever lied, even about "little things?" You are a liar. I could go down a list, but you're intelligent, you get the point. If you are a thief and a liar, how are you also a decent person?
The Bible and the faith you are attempting to mock are very clear about this, all have fallen short of the standards of a "decent" life. All of course means everyone. Guilty of one, guilty of all, essentially. You are a guilty person. You are never un-guilty of what you have done, once you are guilty, you are always guilty. Understand? There is no statute of limitations on guilt.
Equivalency. That's a common practice, but can lead to disasterous results. Christianity and it's Jewish roots have one thing that none of the world's "great religions" can lay claim to- God has told us in advance many things He will do. For example, the caricacture you are making of this symbolic picture, is an artist's depiction of 300 prophecies of the First Advent (coming) of Jesus Christ. Oops, should have said fulfilled prophesies of His first coming. There are 2800 prophecies regarding His Second Coming, many of which have been fulfilled, such as Israel ceasing to be a nation until the time God has determined to bring all the guilty to account, which of course would be everyone, as explained above.After the fulfillment of this prophecy in 70 AD by the Roman Empire, God tells us Israel will become a nation once more. Hmmm, May 1948, in one day Israel became a nation again, just like the Bible said. I could continue, but I know what it is like to be cynical, so I'll leave you with this brief introduction. Let me just say, of these 2800 prophecies, many have been precisely fulfilled, and as the Bible says, they are increasing in frequency and intensity. God is so humble that He sent His only Son to pay the penalty for everyone's guilt, with just a few simple requirements. We must humble ourselves and admit we have fallen short of the requirements of a Holy and just God, we must turn from intentionally continuing to commit those acts, and we must acknowledge and accept the free gift of having a substitute pay for our guilt, that substitute is Jesus Christ. Admit that Jesus is precisely who He says He is, and learn His guidance for a decent life. You know, don't murder, don't steal, don't lie. And when you fail, turn to Him for forgiveness.
