If the jury assigns death, his fate is sealed. But let's address a more important issue here. Certainly, no normal human being pastes on his face a perpetual smile after a loved one, or fellow citizen has been brutally murdered, nor should he. It appears so. Even so, a spirit of revenge does not change the nature of the crime, the proof of the murderers guilt, nor the necessity for proportional justice.
Murder is murder.
The justice of the death penalty is strengthened, not weakened, by the advent of new technologies such as DNA testing, which have recently been utilized to more firmly establish guilt or innocence. It's too late for that. What's past is past. We can't have anarchy. Life imprisonment is a poor substitute for the death penalty.
