Jason's monologue in UTRH was a monologue because that's the only way his voice and his thoughts can reach us in a story that decline his narrative. It was a monologue because that was him confronting and questioning Bruce, the narrative about everything he represents and more. It was a monologue because it represents a shift from a narrative that include everybody but the victim to the victim's narrative.
It was a monologue because it was Jason forcing the readers and Bruce to listen to his narrative, to see his perspective, do hear about his thoughts and know about his minds and to see the world the way it is. It was a monologue so we could understand Jason. It was a monologue because it was truthful, honest, sincere, and it was a monologue because-
Because it was not a dialogue, because a dialogue would require Bruce to respond to Jason with the same level of effort that Jason did, but he didn't. It was a monologue because this guy is pissing you off when Jason was standing there, fighting tooth and nail for Bruce to understand him and he made an effort to understand Bruce, to hear his reasoning too; but Batman was pissing you off because not only he didn't make an effort to respond to Jason with the same kind of effort that Jason did, he also shove away all of Jason's effort claiming that he wouldn't understand.
Jason was showing Bruce his heart bleeing in his ribcage, all his emotions and thoughts and tears and let him and the readers hear the anger in his voice when he said "Why on gods' earth is he still alive?!?" and the tremble in his voices when he said "...because he took me away from you." And all Bruce can answer him is just "I can't"?
He asked Bruce multiple times and wanted to hear from his perspective but Bruce just told him that he won't understand.
He tried his best to, was desparated to understand Bruce and to listen to his reasons and all Bruce did is pulled the cliche "If I do that, I'd never be able to go back." To respond to all the things Jason said! That motivating, moving speech! Just that cliche reasoning. Ignoring what he'd done in the past... I swear that that's not even good enough for the readers and you know that, let alone Jason. He really just went "Yeah I want to kill him I want to kill Joker so bad I really want to kill him I thought about it but I won't anyway."
Jason talked with words, words, moving and powerful and sincere words and Bruce respond with cliche, shallow, useless words like he basically just "I can't. I'm sorry. I just can't." "I'm sorry I failed you, Jason." "Stop this, you know I won't..." "Stop..." "No..." "Don't..."
At least... at least try to respond with some more effort, even just half as what Jason did! It was a monologue because Jason was the only one who was trying to talk and was trying to... try and Bruce was there and he just went I'm sorry I can't don't stop no. Like hello. He was truly disregarding all of Jason's effort and hard work by simply standing there, hemming and hawing, and saying, uhm hmn hnnn I can't. He didn't even try. (Like did he really even listen to Jason's word and let that get into his head, like actually listen and try to understand what Jason was trying to say and his perspective and try to understand why Jason felt that way why he was so angry and how he was showing Bruce how it felt like to be ignored and disregarded as victim, did he even try.)
Jason poured his whole heart into that conversation and confrontation, he was deadly serious, whereas Bruce was just..........
And then he/ the narrative just silenced Jason shut him down wtf ughh I can't.
