Would you still feel the same if the person being put to death was responsible for torturing and murdering your loved ones?

Yes. Some of us apply our moral code universally, rather than letting our feelings decide whether killing people is okay, as long as they wronged us specifically.

Is it uncivilized of a government to consider the victims feelings in these kind of cases?

Yes. Justice systems based on individuals’ feelings are how witch trials work, and it’s how we add more names to this list. Victims’ feelings aren’t evidence, and should not be considered when talking about capital punishment.

Sometimes, the person that you’re 100% certain committed the crime actually didn’t. I wouldn’t be able to live with myself if there was even a sliver of a doubt that we didn’t get the right person. How can I ever know for certain? Even eyewitness testimony is often flawed. Did I see that guy, or did I see someone who looked just like him? I’ve seen my own doppelganger in my city, I know better than to think I can flawlessly identify someone 100% of the time. They confessed? That’s compelling evidence, but again, I know full well that police can coerce confessions. If they maintain that they did it and they don’t feel sorry right up until they die, then maybe I won’t feel bad if my testimony gets someone killed, but otherwise life in prison is an equally effective punishment, with the added bonus that if we were wrong, we can release them and try to find the real perpetrator.
