You honestly think that the Assassins and Templars can compromise? The Assassins want to let everyone control themselves. The Templars want to put control in the hands of what they believe are the responsible few. It is impossible for them to compromise because the scale and points of view they have simply cannot exist together. Combining the two into a middle-of-the-road solution just maintains the status quo and in the end, the Templars will believe it gives too much freedom and the Assassins will believe there is too much outside control. The two of them realize how law functions without their influence. They simply believe it isn't enough.
The Assassins realize that laws are really just words on paper. They do little more to stop people from committing crime than a needle could stop an elephant. What they wish to do is teach people the responsibility they have in determining their own fate. They want people to use their freedom compassionately, not destructively. That is why Ezio told Shao Jun that she would be able to restore the Chinese Assassins through love. Because of this responsibility to use freedom positively, anybody who uses it to commit violence is undoubtedly doing it for their own benefit. No remorse. It is at that point that the Assassins go in for the kill.
The Templars believe that it is human nature to choose the path of least resistance, that given the opportunity they will descend into hedonism. Without social pressures, they will satisfy their deepest, darkest desires as shown in Joseph Conrad's "Heart of Darkness." Therefore, it is the Templar's responsibility to ensure that order is maintained so that mankind does not destroy itself. They think that the Assassins belief that people will exercise their freedom responsibly is too idealistic. And just as parents punish children who use something inappropriately, the Templars will take away freedom to prevent its misuse.
Also, is there any evidence that Haytham reconciled the two ideologies into his own? No, in fact, for the entirety of ACIII he keeps trying to convince Connor that the Assassin's Creed is childish. Haytham is a Templar through and through.
