[Tex/LaTex] How to fully justify the whole document

Question

I want to remove the hyphenation but I don't want to leave spaces in the end of the line due to the removal of the first letters of the last word.
So, I want to make variable spaces between the words to fill the gap let by the removed letters.

My document classe is "report".

Thank you.
