Was the Penalty for Crushing A Man's Testicles Too Harsh?

11    "When men fight with one another and the wife of the one draws near to rescue her husband from the hand of him who is beating him and puts out her hand and seizes him by the private parts,
12    then you shall cut off her hand. Your eye shall have no pity.- Deut. 25:11-12

First off (pun intended) it should be noted that some extra-Scriptural Jewish interpreters believed that payment was able to take the place of having the woman's hand cut off. John Gill wrote regarding Deut. 25:11-12:

 .....though the Jewish writers interpret this not of actual cutting off the hand, but of paying a valuable consideration, a price put upon it; so Jarchi; and Aben Ezra compares it with the law of retaliation, "eye for eye", Exo_21:24; which they commonly understand of paying a price for the both, &c. lost; and who adds, if she does not redeem her hand (i.e. by a price) it must be cut off:
thine eye shall not pity her; on account of the tenderness of her sex, or because of the plausible excuse that might be made for her action, being done hastily and in a passion, and out of affection to her husband; but these considerations were to have no place with the magistrate, who was to order the punishment inflicted, either in the strict literal sense, or by paying a sum of money.

That seems like a plausible interpretation. But let's assume it's a wrong interpretation. How could a Christian respond to the allegation that the cutting off of a woman's hand is too harsh a punishment for crushing a man's private parts? The following is a more developed version of my comments HERE.

Presumably even at this time the Israelites were looking/waiting for the Messiah. By crushing the man's genitals it could prevent or delay the coming of the Messiah because he may no longer be able to produce offspring. So this would be a terrible offense in the eyes of Jews. Presumably, in the eyes of God it could be interpreted as rebellion against and unbelief in God's promise of the Messiah.

Also, just not being able to have children was already a terrible and shameful condition to be in for either males or females in Jewish culture. The man would have this shame forced on him for the rest of his life by the woman who crushed his private parts.

Another terrible deprivation would be the fact that since his testicles were crushed, he would be barred from joining the "assembly of YHVH" for public worship (Deut. 23:1). By the way, this is wrongly interpreted by atheists to mean men with crushed testicles couldn't enter heaven. The law of Deut. 23:1 referred to the earthly religious situation in ancient Israel. Remember, the Old Testament prophet Daniel was likely a forced eunuch and he was well pleasing to Yehovah/Yahweh.

Crushed testicles could also damage his ability to produce sufficient amounts of testosterone and so render him physically weaker. In the harsh conditions of the ANE (Ancient Near East), you needed all the strength, vitality and ambition you could have. Also, with crushed testicles, one might not be able to produce children who were often essential for economic survival. Later on the man and his wife (if he had been married before the woman crushed his testicles) would also eventually need to be taken care of in their old age by children that never existed because of his forced impotence.

Semites understood the connection between testicles and masculinity because they could observe how eunuchs lost muscle mass, lost depth of voice, lost strength, lost aggression, lost ambition, lost masculine features in terms of the size and shape of their skulls and facial hair, penile shrinkage and dramatic drop in libido.
