Evil comes through second causes, as in the case of a good artist with bad tools.

Context

“and even then, we shall not see all of Him. By this vision we become partakers of eternal life, i.e., of life outside time. Divine Providence does not exclude evil, contingency, free will, chance or luck. Evil comes through second causes, as in the case of a good artist with bad tools. Angels are not all equals; there is an order among them. Each angel is the sole specimen of his species, for, since angels have no bodies, they can only be distinct through specific differences, not through position in space.” source
