I think it seems low because of the magnitude of the crime. Also because we punish more violent crimes with very harsh sentences including charging non-violent perpetrators with violent crimes(Felony Murder). Add in the desire to be seen as doing something with sentencing inflation and your get multiple hundred year sentences. At first I felt that 25 years was short but thinking about it, he will be ~60 when he gets out... so maybe not too short.
