The level of risk a pilot accepts in the normal course of his day depends upon what type of flying he will be engaged in.
Helicopter Emergency Medical Service pilots are a much higher risk than Airline Pilots
Crop Dusters are a higher risk than off shore helicopter pilots.
Overall it is a very safe career. However there are segments of this industry that are riskier than others.
If you have an interest in a specific type of flying please ask.
Best of luck in your career choice.
