That depends on your threat model. If you fear juridical problems (say,
for example, some encrypted mails have been intercepted by the police
but they can't decrypt them), destroying the key will prevent you from
having to hand it over. In some jurisdictions this may be seen as
"contempt of court", and even be punishable, but in most EU countries
you're safe when you do this.
