Thanks. The first two are original Google translates which I failed to correct (I realise I was at just that point when the Translate window froze in such a way that only a Windows restart helped & I had to dig all the work done out of a sessionrestore.bak).

On the third, for the ending, can you suggest something not passive (that is, someone has to correct her ways, rather than a correction is needed)?

On the fourth, "system" is way too narrow here; alternatives are "spirit", "nature", "character", "being", "substance".
