Can one’s observance-obedience to the Torah satiate God’s wrath toward our sin and provide an escape from the “second death” in Hell?

No!

Those who seek the Kingdom of God through the Law are under a curse (Deuteronomy 27:27; Galatians 3:10) because the Law mandates perfection if one is to attain righteousness through Law leading to salvation (James 2:10) and all of mankind is under the curse of sin (Romans 3:23); therefore, no one is justified before God by works of the Law (Romans 3:20) as the Law only defines our sin void atonement; It is the shedding of blood that is mandated as atonement for mankind’s sin (Genesis 3:21; Leviticus 17:11; Hebrews 9:22; Hebrews 10) and it is only the sinless shed blood of Yeshua-Jesus who is God and man through the hypostatic union that atones for sin; Only the shed blood of Yeshua satiates the Father’s wrath concerning our sin, not the blood of animals as demonstrated in the Torah (Hebrews 10:4) and ONLY by trusting in Yeshua as our Messiah who died for our sin can we receive the imputation of His perfection over our life and thereby be declared “not guilty” for sin and welcomed into the Kingdom of God where nothing impure is permitted to enter (2 Corinthians 5:21; Revelation 21:27).
