ترجمة - إسبانيّ -انجليزي - odia todo el mundo en estos dias

hates everybody or hates the whole world

If we look at the Spanish version, it's "hates the whole world" because there isn't the preposition "a" after "odia".

Odia a todo el mundo en estos días = He hates everybody during these days.
Odia todo el mundo en estos días = He hates all the world during these days.

I'm not sure if the correction by dramati is correct... Shouldn't it be "During these days he hates all the world"?
