I know this sentence is grammatical, but does it make sense?

For example, if I had a loaf of bread and it was mouldy, would I be correct to say "Ten chleb jest zły." or does it just mean that the bread is evil and shouldn't be trusted?

I wrote 'this bread is angry' - wouldnt it be right...technically?

I think sice zły can be used both for "bad" and for "evil", shouldn't "this bread is evil", although weird-sounding, correct?

What is the exact pronunciation of "zły"? Is it more like 'zuye' or 'zue'? Robot sounds like the latter.
