Sometimes I see people on internet arguing against existence of free will because of Determinism and such, and I never understood the motivation to have such believe.

It doesn't really matter if people actions were chosen on their own accord or if their actions were predetermined. In the end, world will be always in one same state regardless. The only diffirence I can think of is that not having free will remove people from responsibilty for their actions, which doesn't seem any useful or healthy.
