Most religions teach lessons how to understand and regulate human nature. The Christians might call the evil within human nature, the devil within. This, devil within, is closer to the truth, than saying an external object, like money or currency, is evil.
Atheism tends to create projection and make people lose the sense of personal accountability. If money or currency is the problem, it is not my fault if I do terrible things with it, since money has this magic power. It is not about me or something inside of me. It is the currency.
Interestingly, the evil of money or guns tends to come from those who don't like religion but favor atheism. The religious tend to go by the evil within and when this is conscious and regulated, have no problem with these inanimate objects.
The Christian religion, will project the dark side of human nature onto the devil. This has the value of separating the evil from material objects, since the object is material while the devil is spiritual. Atheism will say the devil is a myth and remove this. What is left is the object plus projection; merge again. Although psychology will attempt to separate these.
