(meaning: He was killed so that he would keep silent)
4-He was killed in order to keep him silent.
5-He was killed in order to be kept silent.
6) He was kidnapped to work in a mine as a slave.
7) He was kidnapped to become a slave.
8) He was kidnapped to be exploited in a mine as a slave.
They're all "correct" in the sense that these are all grammatical sentences in English.
The versions of the first phrase with passive infinitive constructions (2,5) sound a bit stilted to me. In general, I would prefer the active counterparts (1,4).
(7) sounds odd to me. Again, there's nothing grammatically wrong with it, but "become" isn't the usual verb for this kind of circumstance. "He was kidnapped and made a slave" or even "He was kidnapped into slavery" sound much better stylistically.
