These are only two laws imported from judaism into islam but nobody would criticise judaism. And besides sharia also include laws that forbid climate destruction that actually kills more people today, it also mandates wealth tax that directly affect wealth inequality.

Regarding death penalty, it is forbiden in sharia to snoop on people. Like you don't go around looking for people to kill, and all the scholars agree it is better to leave someone guilty than to punish an innocent one. So only repeated offenders are caught and even then they are supposed to be given guidance first, and let go. They can also flee the society after that and they shouldn't be pursued. Only the people who stay firm in their disobedience are punished.

And I completely understand you may think even that is unjustifiable. But understand that it is because of how our modern society is today. Roughly 2 out of 3 people in germany commit adultery at least once similar numbers in france. Lying and cheating are not only accepted but justified if its not against the law.

Ofcourse, those laws in sharia can not be applied today but it is way more than just "sharia law wants to kill people"
