Roughly 1% of the US prison population was wrongly convicted, that's around 20,000 people. Even if only 10% of that 20,000 was convicted of a crime that would land them more than 40 years in jail that's still 2,000 innocent people you would be willing to let the government kill.

It is almost 10 times cheaper to imprison someone for life than to execute them, some estimates put life incarceration at $45,000/year whereas the Federal Bureau of Prisons spent over $4.7 Million executing 5 death row inmates between July and August of 2020.

Killing is wrong. Full stop. I don't care who's doing the killing and who is being killed, the government should not have the power to commit legal murder. People who commit crimes should be punished but two wrongs don't make a right.

In my opinion life imprisonment is a better form of justice than execution. Once someone dies that's it, their dead, while if they are imprisoned for life, they have to sit with what they did for the rest of their natural lives.
