The passages are of contrasting opposites.
45:6 - That they may know from the rising of the sun (east)
and from the west,
that [there is] none beside me. I [am] the LORD, and [there is] none else.
45:7 - I form the light, and create darkness:
I make peace (shalowm - (social) tranquility),
and create evil (ra - calamity/adversity):
I the LORD do all these [things].
Evil is the contrasting opposite of good, not of peace.
And moral evil is nothing that was created.
It is the absence of moral good.
Calamity He created for chastisement includes the destruction of Sodom and Gomorrah, and The Great Flood.
