I already told you this. Look one or two posts back when you first asked. The very first thing I said was "God." So yes, it 'springs' from God, it necessarily must as He is the ontologic fundamental (everything must spring from Him logically).

If you want to go deeper into it, I gladly will, but to summarize, God created the conditions of morality (necessarily if God exists as that which is the creator of all subsistent things). This is why some go into privations; God didn't create in the first order 'evil' itself, He created the conditions of reality, part of which is lesser beings of will which can go against the ordering He created (and wants, but not wills, if you will, for us to follow). You could call that ordering arbitrary in the strict logical sense, but you could never validate that as again it would be another blind hypothetical for which we have no frame available to consider (which has been coined 'mystery' in the proper sense but the term is often used foolishly for non-mysterious things). But going infinitely down that 'why' path into the mysterious is also a 'What if?', not a 'What is?' and is irrelevant ontologically (or at least it is once you understand the certainty you can hold of an ontologic fundamental).

A lot of people get hung up on 'evil' for one of two main reasons: emotion and difficulty with multivariate logical regressions. On the former, it isn't a problem of logic and I am not really the guy to help you. On the latter, it is often difficult to think of terms properly merely as amorphous concepts which we try to bound well enough. Evil doesn't make reasoned sense without Will (nor Will without Evil or at least wrongness), neither of which can be reasoned without God and the contingent supra-conditions of reality (physical nature etc.) because there would be nothing for us to will within and therefore no evil would exist. Take God out of it and just try to reason out evil itself to some fundamental. Most people end up at nihilism (even though it is logically barren) and conclude a relative moralism, but they don't have to because you can be certain that God (as ontologic fundamental) exists.

So yes, God 'created evil' insofar as it is a possible path for lesser beings of will. This only gets more difficult when you start to consider epistemological concerns in that logical regression (But Christ made it very simple, it's not the conduct, but the effort).
