Bot lane please

I recently had a game with bot morde and aurelion supp Morde got a very lucky clean up for a few doubles end game so ended witha kda of 7/13/6 Aurelion 1/15/11. Granted they also didnt push much, attempted to take objectives without me (the jungler) I was pushing their turrets as i saw them going for rift herald, i ping them to back off, what do they do? They dont, they get caught by the lucian that they gave 20 kills to prior 20. And then flamed me. In all this im confused because i ask them to play passive, they kept dying repeatedly. I came to gank and they still died. They just couldnt play passively at all. At the end of the game they say "report diana" ofc theya re premades but the enemy team saw what i dealt with and instead honored me (which was kinda funny tbh) Anyways, post game i ask the one that stayed behind (aurelion) why he was 1/15/11. Their response? "I play blitz more but he was banned" FFS HOW DOES THAT EXCUSE YOU DYING 15 TIMES. I will never understand . Like if i ever die past the 10 mark, i always feel bad and look at what i did wrong. But every bot lane i see plays the victim blame game
