This sentence (even if you can beg from him) appeared in different times. It was an era of stressing spirit and shouting slogans. Now is a material age, so this sentence no longer works. Nowadays, people are used to the lifestyle of material enjoyment. If you don't let him live like this, you might as well let him die. In addition, I think the pursuit of material enjoyment is also an instinct. This is reasonable. Just like animals.
