First, I don't think you want to depend on the bad guy to see the laser. They may not and you want a fast reaction time.
Second, for self defense, you shouldn't be pointing the gun in most jurisdictions until you have justification to shoot. Do you want to wait for the threat to get closer or attack again in the hopes the laser works as a deterrent? I think it is a case of being great if it works, but I wouldn't wait around for it.
Third, I don't have a laser on my current carry gun. Yes, they are not necessarily pin point accurate, but they can help in some situations and/or with some shooters. I had one on a small 40 S&W pistol and I thought it helped speed up my follow up shots as I could see the laser drop down on the target and fire again before I reacquired the sights. I think that will depend on the level and skill and experience of the shooter. I have heard really good things about them for newer or less experienced shooters. You have to decide where you stand with that.
Fourth: I have heard it is common for people in stressful situations (gun fight?) to just aim along the top of the gun and not see the sights. Tom Gresham has mentioned this when talking about his First Person Defense videos (mostly less experienced shooters). A laser is going to help in that situation.
Fifth: The part that always got me is the laser costs some money to get, but you may also need a different holster with some of the lasers. I have had issues before finding a holster in the style I preferred for the gun I had. If they are the lasergrips, that may not matter. If it is the rail mounted laser, it might matter.
Last, most examples I have played with are not pin point accurate and can shift point of impact some, but if you are trying to hit a pie plate or a man-size target at 15 yards or less, they are plenty accurate for that.
