While fixing setup, usually, we fix for different corners. fixing dominant corner would have helped other corners too.. What is the point, we consider for fixing other corners as well??

Cool ,... see we need to fix the setup and hold every where means for every corner. Now if you will fix it in one corenr then it may create issue in other corenr. So its better to fix it every where.
Now as you as asking that if we fix it in the dominating corner, then why to fix in in other corenr. So my question is .. what do u mean by dominating corner? In lower technology you cann't say that there is a single dominating corenr for entire design. May be for One net/part of design.. one corenr is dominating and in other part of the design, other corner is dominating.
so its always better to fix it in all the corenr.

Let me know if you have any specific doubt in this.

Generally we define a corner 10% below the working point we want the chip works. Then if you have many working points, you could check all of this points to "guarantee" the timing at this "require" points.
