Somewhat. I'd much rather just amend the Constitution, but that's a slow and unreliable process. I do not see it as inevitable that the Supreme Court will just get rid of it. The Constitution specifically mentions capital crimes so it cannot be argued that the DP is inherently cruel and unusual or otherwise prohibited by the Constitution - sure some people try to make that argument, but like all people that try to cherry pick only the parts of the law that suit their argument, they're wrong. An amendment is the only way to go, and frankly we should be making more use of the amendment process instead of treating the Constitution like some religious artifact that's going to disintegrate if we alter it.
