All I'm saying is that it's probably not a good idea to leave it to the screaming masses who scream "Give him what he deserves!" That is tyranny of the mob, which is not what rules in Taiwan.
If you look at the death penalty in Taiwan there was a temporary moratorium which was leading to abolition. That was ended due to pressure from public opinion

In May 2008, Chen Shui-bian's successor Ma Ying-jeou nominated Wang Ching-feng as the Minister of Justice. Wang also held an anti-capital punishment standpoint and delayed every death case delivered to the Minister's Office. Until March 2010, a total of 44 Supreme Court's condemned prisoners were detained by the Ministry but Wang still publicly announced her strong attitude towards anti-capital punishment during media interview. This caused controversy and the consensus suddenly broke out after entertainer Pai Ping-ping (whose daughter Pai Hsiao-yen was kidnapped and murdered in 1997) held strong protest against Wang. Wang, who originally refused to step down, resigned out of social pressure on March 11, 2010.[41] Wang's successor Tseng Yung-Fu(曾勇夫) promised to premier Wu Den-yih that he would resume executions
I don't think the masses - in either the UK or Taiwan - are as 'screaming' as you say. The difference between Taiwan and the UK is that in Taiwan listen to them and in the UK they do not. Public opinion in the UK supported the death penalty for decades after abolition and the political class simply ignored it. And in fact denigrated it as 'the screaming masses'. Meanwhile the homocide rate approximately doubled. Though the political class live in a bubble of police protection and expensive areas and don't experience it.
The same thing happens in Canada with NCR - public opinion is opposed to the scheme but the political class sneers at it as being ill informed.
This sort of thing is very dangerous for democracy - if people feel they are ruled by a political class which ignores their interests, cripples the justice system and leaves them at the mercy of criminals that increases the chance they'll vote for someone - anyone - who can change things. I.e. the political class may find itself by an outsider party. And that outsider party may be really irresponsible - e.g. the neo Nazis, Islamists, etc.
