Burst capillaries are what causes bruises.
It depends more on the amount of blood loss more than anything else. If an artery explodes get to an emergency room, because the arterial pressure is greater, the blood squirts.
With veins, the venous pressure is less, so you may live if one explodes, it depends on the size of the vein how much blood you will lose getting to the emergency room.

In a nutshell, yes. There are a lot of factors to consider - the size / diametre of the vein, proximity to major organs, other injuries . . .
Strokes (or CVAs) occur when a vein or artery suffers an aneurysm in the brain. This is similar to seeing a bubble form on the garden hose where the wall has become weakened. The wall of the blood vessel weakens causing a haemmorage (or explosion) into the brain. Sometimes strokes will kill a person, other times it can cause life-altering changes, and still others cause almost no perceptible damage.
A bruise (aka a contusion) is the rupturing of vessels (usually capillaries, but also veins or arteries depending on the depth of the injury.)
One last note . . . uther_aurelianus mentioned that veins carry blood that is depleted of oxygen. That's mostly true - veins carry blood back to the heart. Most of them carry deoxygenated blood, but the pulmonary veins leading from the lungs back to the heart carry blood that is oxygenated.

Sorry modulo, but capillaries are smaller than veins. Veins are the blood vessels that transport blood that is exhausted of oxygen. If a small vein breaks, than usually you just get a bruise, if a large vein, such as the jugular in your neck, ruptures, you could die. Even if an artery is ruptured, you may not die.
With modern medicine, people can be saved even with severe blood loss. Unfortunately, the more blood lost, and the longer it takes to get to a hospital, the less chance for survival. In EMS, (Emergency Medical Services) we have what is called the "Golden Hour" for trauma cases. We want to have our patients in the hospital within one hour of the incident occurring.

It depends. If it is a capalary(a very, very tiny vein) not much will happen. If it is a large vein or a artery and you do not do anything about it you probably won't survive.

As said before, depending on whether its a capillary, small vein, or a larger vein. If it's a larger vein, it could cause death.

Shorty is right. veins are the smallest part of the blood flow system. They break all the time.
