I don’t think you all understand how tragic achilles and patroclus was
in the original version of the iliad, after the death of patroclus, achilles is so enraged that he just kills every enemy in sight, literally a bloodbath is what happens, i’m pretty sure the description says something like the waters were turning red and were more blood than water
it becomes so bad that a river god actually appears to him and commands him to stop his raging
and what does achilles do?
he slaughters the river god who dared to temper his anger, because nothing can console the agony he is experiencing in the death of patroclus
he drags hector’s body around the walls of troy, completely desecrating it and preventing his family from giving him a proper burial
it isn’t until he sees the love that priam has for his son that he returns the body because while it is a different love, the grief priam is experiencing is something he recognizes
