Franz Ferdinand was a genuinely decent human being by all accounts. He was widely respected in Europe and the world for his character and his humanity.
Not really.
Emperor Franz Josef had no respect for him at all, and didn't mourn his death one bit. He also enjoyed little popularity among the Austro-Hungarian people, and was often ridiculed in newspaper cartoons (due to his supposed appalling temper). He already had an official portrait of himself painted wearing the Imperial regalia, despite the fact that Emperor Franz Josef wasn't even dead. He was generally believed to be the leader of the 'war party' calling for Habsburg military adventurism and militarism. (Conrad was a close ally of his).
As for the Archduke's 'character and humanity', here are some examples:
Franz Ferdinand on the proper role of the army: as a weapon against the 'internal enemy' , which comprised 'Jews, Freemasons, Socialists and Hungarians'.
More of his feelings on his loyal Hungarian subjects: "Every Hungarian, be he minister, prince, cardinal, citizen, farmer, hussar or a servant, is a revolutionary and a whore. Alright, the cardinal is no whore, but he' a republican nonetheless."
Franz Ferdinand on the people of Bosnia after the 1908 annexation: "Now, however, the main thing is to keep the peace in Bosnia with an iron rod. Any attempt at a putsch or an infiltration by the [Serbs] from across the border must be met with execution by shooting, hanging, etc. We have to keep a particularly tight rein in the Serbs in Bosnia, keep them frightened."
Finally, an illustrative anecdote. In 1906, the Serbian army was in the market for artillery. Franz Ferdinand forced the Austrian government to issue threats to Serbia, up to and including economic sanctions and a trade blockade, if they didn't buy Skoda guns. The fact that the Archduke would personally make a huge profit from this contract may have had something to do with this... Unfortunately, the Serbs defied the threats and bought French guns instead: and this crisis permanently damaged relations between Austria-Hungary and Serbia.
In short, he undoubtably loved his wife, but he was certainly no saint...
