Abolish Death Penalty

I am against of abolishing death penalty. The criminals who were sentenced to death must commit the serious and unforgivable crimes that mean there is nothing can substitute for their crimes and be held accountable for the victims but sentence to death. If we abolished death penalty, it were not only relating to the criminals and victims but also influencing the whole society. For instance, in Taiwan, the judiciary system is not enough to guarantee us against injuries and sustain the safety of our society when we abolished death penalty. On the other hand, according to numerous cases, study shows that the criminals who are released and return to the society, only few people are willing to change themselves; most of them will just recommit crimes and are sent to jail again. How come if we released the criminal who was sentenced to death, the causes, and the effects are no one could undertake and expect. Therefore, I think it is unnecessary to abolish death penalty.(166)
