Yes, that's what I ment - the ATC put unnesesary pressure to the poor pilot.

The ATC instruction was perfectly normal, and did not in itself put
unnecessary pressure on the pilot. The ATC wanted to avoid an imminent
collision. The apparently pilot did not react for something like 20
seconds after the ATC's instruction, instead continuing at the same
altitude, which is why the ATC had to repeat it with greater urgency.

By playing the "authority" too much, he forced the pilot into taking his
advice as one that is overriding, so the russian pilot flew into the other
aircraft -

The ATC did not force the pilot into taking his advice. If the pilot
had proper training, he would be able to sort out conflicting
instructions. That is not the ATC responsibility.

this is why I call the ATC murderer.

As I said before, murder is premeditated. The ATC did not plan on
killing anybody. You are therefore wrong not only on your
interpretation of the events leading up to the accident, but wrong in
the use of that word.

If the russian pilot had made a mistake, be it because of CRM
issues or other, I could have said that he is a fool - but
he is not. That's sad!

How can you come to that conclusion? The events as reported so far are
somewhat sketchy, and there certainly hasn't been any official report
issued that reviews the individual actions of the ATC or pilots, nor can
we be sure that the TCAS functioned properly when both planes started to
descend. (The latest TCAS systems are supposed to change RA if one of
the aircraft doesn't respond as it should.) Therefore, you cannot come
to any conclusions whatsoever about who was right or who was wrong,
except for misinformed ones.
