I know one of the fundamental principles of Christianity is that Jesus' sacrifice means that, if we renounce our sins, we can theoretically all be absolved of our them, but I was wondering if you could view personal circumstances as making a sin less grave in one person than in another.
Let us take, for example, a poor, starving family who's provider is forced to steal to survive, and when they steal they make sure it's from people who can spare the supplies. The provider is breaking one of the Ten Commandments. Are they better or worse than someone who breaches a lesser commandment for no good reason?
What about the soldiers in the trenches in World War One? The conditions were absolutely abysmal, particularly for the French, British and British Colonial troops during major battles such as that of the Somme (the Triple Alliance (mainly Germany and Austria-Hungary - sorry for double brackets) had better trenches, albeit with inferior food). For a tiny scrap of relief in the four long years the war lasted, many of them visited prostitutes (thus committing adultery) or engaged in activity viewed as sinful. But are they as sinful as someone who does that in peacetime?
