There is a school of thought and experience that recommends not deleting images from your camera with the trashcan or delete button on the camera itself - only use the reformat function in your menu. An image may look poor on the back of the LCD screen, but on the computer it may be just fine. So it is best to analyze the images on the computer screen itself rather than the back of the camera.
There is the chance that some corruption may occur on the card itself by using the camera’s trashcan/delete button. After copying (not moving) the images to your computer or backup device, and you are certain that you have good copies of the photos, then reformat the card in the menu function of your camera.
Another good safety tip is NOT to use your card until it reads "full". Instead, change cards before that message.
