Sometimes. Although they shouldn't. Most digital images require a certain amount of sharpening. Unsharp Mask is a good tool. It provides some edge contrast to give the apearance of more sharpness. You should apply it to images while viewing at 100%. If you see too much edginess and sparkle in highlights, you may have gone too far. If you see halos, you definitely went too far.
Later versions of PhotoShop also offer Smart Sharpen. This tool allows you to correct sharpness in different ways. It recognizes that lens blur, our of focus, and motion blur are different situations, and sharpening is applied in different ways. Experimentation is your friend here.
