doing or undergoing something

[Filip]

Hello,
I would like to know whether my assumption about the following
is right or not:

If I say "Kenneth had his best friend killed" it means that Kenneth
asked someone to kill his best friend for him.

But if I say "Kenneth had his best friend kill for him" it means that Kenneth
asked his best friend to go and kill someone else.

So in general, in a sentence like "A had B killed/fired/thrashed..." (when
I use a past simple for the verbs kill/fire/thrash...) it means that B undergoes something that A set in motion.

And in a sentence like "A had B kill/fire/thrash C" (when I use a present tense for the verbs kill/fire/thrash...) it means B does something to C because he was told to do so by A.

Can anyone verify this for me, please?

Filip,
You understand, and express, the meanings quite correctly. Just one minor quibble: the verb forms "killed," "fired," "thrashed" are not past tense verbs - they're passive participles. And your "kill," "fire," and "thrash" are not simple present tense verbs - they're what grammarians call "bare" infinitives.
You write English very well. You'd get an A in my class.

Hooray, an A! That means a lot to me, coming from a true English speaking teacher. Thanks very much for confirming my theory and teaching me the correct grammatical terms that came with it.
