'Pope' Francis supports call for "freedom from unjust social structures". How about Israel's enslavement for 400 yrs+?

'Pope' Francis thanked Dominican 'Father' Gustavo Gutierrez for his contribution to the 'liberation theology' in the call for freedom from unjust social structures. 
It is clear that 'Pope' Francis supports the call for "freedom from unjust social structures". 
(...but didn't Lord Jesus say to serve in obedience, to do good to, even the unjust rulers and masters?)
Would the 'Pope', in that case, make the same 'call for freedom' for the Israelites from their "unjust social structure" of enslavement for over 400 yrs by Egypt?
He would, since he believes in FREEDOM.
But ironically, it is the 1God that caused them to be enslaved for over 400 years. 
Therefore, their enslavement was not unjust in God's eyes.
But the 'Pope' believes in FREEDOM "human rights, human justice".
Why did the 1God do this?
...the Israelites started to worship other gods after the death of Joseph.
...the Israelites rebelled against and disobeyed the command to worship ONLY the 1God....claming therefore "FREEDOM" to worship any & other gods.
...And in the name of this FREEDOM, they even forgot (rejected) the name of the 1True God.
See the power of this "FREEDOM"....for man worships it as a "light"....so as to serve and magnify oneself.
But the judgement of the 1God is just.
