Death for pedophiles?

Last year, Trump tweeted out that "pedophiles" should get a fast trial and a fast execution. I am opposed to this. I once blogged about a young couple who were being prosecuted because they took revealing photos of themselves and texted them to each other. They were caught, and being prosecuted as adults for possessing, producing, and distributing child pornography. Should they be put to death?
What about the 14 year old girl who sent revealing photos of herself to her boyfriend? Should she be put to death? In this particular case the ACLU is defending her (even though I abhor them, the occasionally do some good).
It is unlikely that such a law would be constitutional, as the Supreme Court already ruled in 1977 that the death penalty was excessive for rape.
Not only that, but I am opposed to the death penalty because I don't trust the government to be honest.
