Evolution has nothing to say about morality and does not care about suffering. There are millions of evolved creatures who die horrible deaths every day. There are also countless species who no longer exist because of evolution.
Science likes to have a crack at the morality problem but lacks the tools. Having said that, advances in science have reduced human suffering immeasurably.
We made a lot of progress in that. You are underestimating science overly here.
The fact that there seems to be no "order" in life and death doesnt suggest a simulation. Greed rules the world, the world is being overrun by greed. This is a fact.
