A wise and powerful general who was determined to bring an end to the wars that had plagued his homeland for decades, in contrast to his peers, who just wished to fight and conquer for themselves.

His dedication and vision earned him numerous followers who would give their lives for him and his cause. Toyotomi Hideyoshi, Sengoku Basara.
A dedicated mother with an abusive, philandering husband who cries out another woman's name during their first night together; although she, too, is unfaithful to their marriage, at least it's with someone she truly loves, rather than whatever pretty face suits her on any particular night.

A magnificent genius who has kept his kingdom's coffers liquid for years despite his king's propensity for spending lavishly, even frivolously.

After his kind discovers an energy source that defies the Law of Conservation of Energy, he and his fellows set out to harvest that source in order to stave off the heat death of the universe.

Scrupulously honest, there's no evidence that he's ever told a lie. Finally, he goes about his business with an unfailingly cheerful demeanour. Oh, and he really, really loves entropy. Maybe you've heard of it? Kyuubey, Puella Magi Madoka Magica.
A young prince who actively implements his father's policies in the province he has been charged with governing. He is also a dedicated patron of the arts and, indeed, an artist himself, and beloved of the most significant section of his people. Moreover, he loves his family dearly, particularly a certain half-brother and half-sister of his (despite the fact that he always lost to that same half-brother, several years his junior, at chess), whose tragic deaths motivate him for the rest of his life. Sadly found himself in over his head after a group of terrorists stole a top-secret research project, though he did his best to recover the project and minimise its exposure to the general populace. At this point, though, he was assassinated by a masked terrorist who went on to effectively destroy the prince's entire nation. Clovis la Britannia, Code Geass.
A highly talented young man who found his country plunged into chaos and civil war by the corruption and incompetence of the ruling classes. Making the most for himself in this time of strife, he rose from being an humble civil servant to being the most powerful figure in the land, holding the second-highest office of state, though he made a point of never going so far as to usurp the head of state's own office. A dedicated meritocrat, he made a point of placing ability above all else in his subordinates, and made sure always to treat them well and reward their successes. In a similar vein, he took a supremely even-handed approach to justice, allowing no familial or political connections to excuse a law-breaker of punishment. He could very arguably have reunited the land in his own lifetime, thus sparing it several more generations of ruinous civil war, but he was thwarted by an insignificant scion of the imperial family who believed that, just because he had some imperial blood in his veins, he was more suited to ruling the land, even though, by the same argument, there were numerous closer relatives alive who should've have precedence over him, along with the jumped-up second son of a regional governor who never demonstrated any vision for uniting the land. After his death, he was unfairly vilified for generations afterwards, even, to some extent, to this day. Cao Cao, Romance of the Three Kingdoms.

An incredibly talented young man whose entire life was centred around self-improvement.

Was, in the end, defeated by the machinations of a fellow scientist with good cause to be jealous, whose only other motivation was the preservation of the status quo; he fittingly calls said fellow scientist out on this. Though speculated by The Hero to be extremely lonely, he never let this show and maintains a calm, pleasant demeanour almost to the end. Aizen Sousuke, again of Bleach.
A brilliant young man who seized power in a virtually bloodless coup d'état with the intention of abolishing the imperialist, Social Darwinist regime that had previously prevailed in The Empire which spanned roughly a third of the world's land surface; despite fierce resistance from its aristocracy, he succeeded.

Ultimately betrayed by his lieutenants and forced to commit suicide while all that he had worked for laid in ruins around him. Adolf Hitler.

He's affable, funny, and friendly, and both times he had a chance to kill the main character, he didn't.

Gin Ichimaru of Bleach.
He prevented a nation from falling apart for probably around 40-50 years with the only way he knew how to, which had been passed down to him by the truly evil ones who were so twisted as to come up with it, knowing full well that whoever came after them wouldn't be able to dismantle their system even if he/she wanted to, because the minute the people were free, they would rise against the current leader, regardless of whether or not they had come up with the system. President Snow from The Hunger Games.
