Suffering isn’t good. The growth that can be achieved through suffering can be good. There is a very big difference. Suffering doesn’t guarantee growth. Experience gained through suffering might not always be good (we may become jaded or cynical, or worn down).

Putting that aside for now, hurting others is bad. Inflicting suffering on others is not good, and doing so to try and force “personal growth” in a direction you desire is absolutely not good. That’s strange, cruel, controlling behaviour. That’s sort of like playing god.

When people say that suffering builds character, or reference bible passages like Romans 5:3 (And not only so, but we glory in tribulations also, knowing that tribulation worketh patience;) (apologies, I don’t know similar teachings from other faiths although I’m sure most faiths have a similar concept to this somewhere in them), they are typically talking about a sort of impersonal “suffering”. The death of a parent, sickness, poverty, that kind of thing – and crucially this idea is often separated from “blame” and is instead a sort of “faceless” suffering. It could be set up like this so that people can focus inwards or on something spiritually, rather than getting stuck in a cycle of blame or revenge, but other times the suffering in question is literally blameless, such as a parent dying of old age.

Either way, the key part in your question is that experiencing suffering is an unfortunate but inevitable rite of passage, and hopefully a person will learn and grow as a result, but that intentionally causing suffering is a choice to hurt another human and is bad. It’s sort of two separate things, really.

I’m aware that I answered a slightly different question, but I’m not sure I understand what you mean when you say suffering is good because it “gives life meaning”?
