Those verses don't say anything about equal punishment. Do you actually believe that an alcoholic faces the same punishment as a serial killer?
This verse indicates different levels of punishment just like there are varying levels of reward in Heaven.
Luke 12:42-48
And the Lord said, “Who then is the faithful and sensible steward, whom his master will put in charge of his servants, to give them their rations at the proper time? Blessed is that slave whom his master finds so doing when he comes. Truly I say to you, that he will put him in charge of all his possessions. But if that slave says in his heart, ‘My master will be a long time in coming,’ and begins to beat the slaves, both men and women, and to eat and drink and get drunk; the master of that slave will come on a day when he does not expect him, and at an hour he does not know, and will cut him in pieces, and assign him a place with the unbelievers. And that slave who knew his master’s will and did not get ready or act in accord with his will, shall receive many lashes, but the one who did not know it, and committed deeds worthy of a flogging, will receive but few. And from everyone who has been given much shall much be required; and to whom they entrusted much, of him they will ask all the more.
