How to be a religious hypocrite

What's the difference between Judaism, Christianity and Islam? They all worship the same God. More than that, they all follow the same Commandments from the Old Testament. The 6th Commandment says "Thou shall not kill" (albeit with slightly different expressions depending on which book you read). The reason I wrote this comic is because of all the contradictions and hypocrisy around religion. Men that claim to follow their faith to the letter of the law ignore the dictums laid out to them when it doesn't suit their needs. Maybe one day they'll come to their senses. Until then, I guess we'll have to rely on the wisdom of little yellow men from outer space. (Oh dear, have I just committed heresy?)
