Is it right to still blame germany for ww2?

I suspect you're confusing your empires. For all I know, there may be people who believe in a counter-factual version of history where the evil, Muslim Turks were pulling the strings behind the scenes, but it's generally accepted that the actions of the Austro-Hungarian Empire were the direct cause of WWI. It is a fact that, as Austria-Hungary's much more powerful alliance partner, Germany supported Austria-Hungary responding in the most aggressive way possible to the assassination of Archduke Franz Ferdinand by declaring war on Serbia. The Kaiser knew Russia would respond to this attack on one of its allies by mobilising, and he also knew that the interlinking treaties between the major powers of Europe would likely lead to a major conflict. But Wilhelm and Germany's political and military leadership were eager to go to war, they were certain that Germany would win, and so they were fine with this.

The Ottoman Empire was involved in WWI and it did side with the Central Powers, but its involvement was pretty peripheral, largely because it - like Austria-Hungary - was heading for collapse before the war due to internal tensions.

Given what I know of your political views, I'm not surprised that you slip in the far-right wingnut trope that the Nazis were socialists, but that's counter-factual too. The title of the party was indeed National Socialist German Workers' Party, but naming your pit-bull Hamster does not make it a harmless, fluffy little rodent. The Nazis were ultra-nationalist, socially conservative, anti-egalitarian, anti-trade union fascists. All that was exactly the opposite of what socialists believed in prior to the formation of the Nazi party, and still do.
