so far I've played Dynasty Warriors (the entire series) and read Romance of the Three Kingdoms. From what I have read on here is that Ding Yuan was not Lu Bu's adopted father, and that a lot of people have a negative view about Lu Bu. On the other hand, when i read Romance of the Three Kingdoms like 12 times, Lu Bu only left and killed Ding Yuan because he was easily persuades and was complimented for his prowess, then when he was with Dong Zhou, he was threatened for messing with one of the Hand Maiden's (which I'm presuming is the person Diao Chan is based on) and had a spear thrown at him. He sounds pretty loyal to the Han as he technically never revolted against it. Wang Yun basically convinced Lu Bu that Dong Zhou was a tyrant, would threaten him more and was destroying the Han.
I'm guessing the only reason why Lu Bu still fought for Dong Zhou at Hu Lao Gate was because he thought the coalition was trying to overthrow the emperor? After killing Dong Zhou he went to Yuan Shao but Yuan Shao was suspicious of Lu Bu therefore he fled for his life. After being defeated by Cao Cao at Dingtao, he became Liu Bei's subordinate. This is where I remember reading that while Liu Bei went off to fight somewhere, he left Zhang Fei in command of Xia Pi where Zhang Fei also promised not to drink because of how he gets. Zhang Fei did in fact go back on his word and got drunk, beat Lu Bu's relative that was there after refusing to drink. The relative apprently went to Lu Bu and told him the story to which infuriated Lu Bu and caused him to confront Zhang Fei. Since Zhang Fei was Drunk, he most likely took this as Lu Bu rebelling and then we all know how Liu Bei found out but only Zhang Fei's side, so Liu Bei goes to Cao Cao and then the whole Seige of Xiapi happens.
The Sanguozhi stated that Lü Bu surrendered when he saw that he had been surrounded, instead of him being captured by his own subordinates who had betrayed him. His final words, said to Cao Cao and Liu Bei moments before his death, were similar to those mentioned in the Romance of the Three Kingdoms. Cao Cao then had Lü Bu hanged. He ordered Lü Bu's dead body to be decapitated and the head sent to the capital Xuchang and later had it buried. Lü Bu's biography in the Houhanshu mentioned that Lü Bu asked his subordinates to take his head and surrender to Cao Cao when he saw that he had been surrounded by Cao's forces. However, his subordinates were unwilling to do so, hence they surrendered together. The rest of the account is similar to that in the Sanguozhi and its annotations.
Lü Bu was tied up and brought before Cao Cao. He said, "I'm being tied up too tightly. Can you loosen the bonds?" Cao Cao replied, "A tiger must be tightly restrained." Lü Bu then said, "My lord, you dread only me, but now, since I've already submitted to you, you shouldn't have any more worries. My lord, why don't you spare me and let me help you lead your troops? In this way, you won't need to worry about not being able to pacify the Empire." When Cao Cao showed signs of reconsideration, Liu Bei said, "My lord, haven't you seen what Lü Bu did to Ding Jianyang and Grand Preceptor Dong?" Cao Cao rubbed his chin. Lü Bu shouted at Liu Bei, "You're the most untrustworthy person!"[Sanguozhi 24]
Additional details about the conversation between Lü Bu and Cao Cao were recorded in other texts and they were later added by Pei Songzhi as annotations to the Sanguozhi.
The Yingxiong Ji recorded:
Lü Bu said to Cao Cao, "I treated my subordinates generously, but they betrayed me when I was in trouble." Cao Cao replied, "You abandoned your wife, and you have designs on your men's wives. You call this 'treating them generously'?" Lü Bu remained silent.[Sanguozhi zhu 18]
The Xiandi Chunqiu recorded:
Lü Bu asked Cao Cao, "My lord, you've lost weight. Why?" Cao Cao asked him, "How do you recognize me?" Lü Bu replied, "When I was in Luoyang, I saw you at the Wen Family Gardens (溫氏園)." Cao Cao said, "Yes, I forgot. I lost weight because I'm depressed over not having recruited you earlier." Lü Bu said, "In the past, Duke Huan of Qi forgave Guan Zhong for injuring him earlier and even appointed Guan as his chancellor. Now, is it possible for you to allow me to do my best to serve you?" As Lü Bu had been tightly restrained, he turned to Liu Bei and said, "Xuande, you're a guest here. I'm a prisoner being tied up. Why don't you say anything to help me?" Cao Cao laughed and said, "Why do you turn to him instead of speaking directly to me?" Cao Cao had the intention of sparing Lü Bu so he ordered his men to loosen Lü's bonds. However, Wang Bi (王必), a Registrar (主簿) under Cao Cao, interrupted, "Lü Bu is a powerful foe and his subordinates are nearby. He should not be spared." Cao Cao then said to Lü Bu, "I wanted to spare your life, but my Registrar says no. So, what should I do?"
so i guess what I'm trying to get at is, can we really say that Lu Bu was greedy, savage and traitorous to the max and was simply not given the opportunity to state his side of the story?
