Here are a few things I believe alien intelligence may benefit from knowing about humans:
Humans are meddlesome trivial scamps.
Their thoughts feelings and beliefs are a threat to others.
Man is savage and beastial, and must be dealt with so.
Savage power is mitigated by a civilizing accord. A righteous rule (lawful behavior) is that civilizing accord.
Extend every right privilege and validation to others as one grants unto themselves (whoever they may be.)
This is how ascendant beings must behave.
What preconditions are required to make any of your claims true? Even if your claims are true, are they changing the behaviour or are they changing the fundamental view that drives the behaviour? Because to me, it looks like only the behaviour, which makes it somewhat irrelevant as far as driving understanding. If the species we encounter evolved under competition and scarcity (likely) then none of this invalidates the concept of understanding us trying to kill them as the basis of the beginnings of understanding each other.
What do you think an ascendant being is?
Ascension is to be the fullest self. Ascendency is to go beyond the self. Not all ascendant beings are honest, moral or lawful (I am, honest to a fault.)
It is reprehensible to think you should try killing strangers because you cannot communicate with them. (Consider if I advocated killing you for speaking so foolishly.)
See them as your equals and negotiate for territory like everything else.
