For killing v. having killed

Question

If the sentence  is "Elle finira en prison pour avoir tué son amant." ....why does the English translation say "She will end up in prison for killing her lover" and not 'She will end up in prison for having killed her lover"....?

Anne Davies · Accepted Answer

Think it’s because "for killing" and "for having killed" have an equivalent sense in these English sentences and both are translated into French as "pour avoir tué".
The construction is similar to "après avoir + past participle" = after doing/ having done

In this case, English isn't as precise as French. Note, though, that "...for having killed her lover" is a more literary form in English and certainly also more precise even though it isn't heard as frequently in everyday spoken English.
