[Avodah] yosef

[Eli Turkel]

<<And in truth, even though all the commentators on the Torah have
already written that the quarrel between Yosef and his brothers was not
a quarrel rooted in jealousy and hatred between them, but it was a
disputed Le'Shem Shamayim over the Ikar Ha'Din, that the brothers ruled
that Yosef was pursuing [Rodef] them and it was therefore permitted to
kill him,>>

Why does the piyut on asarah harugei malchut say that these 10
were the first capable of being a kapparah when the brothers were perfectly
legitimate in their actions and did nothing wrong and don't need a kapparah
