NEVER use a visual spot as a reason to ignore an RA.
Here is why.
However you may consider turning for additional separation, depending on the situation and your company SOPs. General guidance is that one an RA is underway, the handling pilot should be head in on instruments. However the non handling pilot can lookout depending on the other tasks underway.
However, be advised that a late turn actually increases the collision risk if the aircraft do overlap laterally. But a prompt turn early in the encounter might be helpful.
