So by your reasoning, a person that commits a crime should be put into prison for the rest of their lives, regardless of their crime, otherwise you support the crime right? 😊
Feeling empathy for a person who committed the crime does not make the perpetrator absolved of any wrong doing. To a degree a punishment should be delivered. The punishment must be in accordance to the gravity of the crime.
For granting current illegal immigrants citizenship, what is the punishment for them breaking the law? What I can only see here is absolute pardon.
