The word wicked goes against English common/universal rule that says that after voiceless sounds such as k, the final –ed is pronounced like t. Note that the -e remains silent. "Wicked" ends in a k sound followed by a d sound as a result it was supposed to be blended/wɪkt/ not pronounced as an extra syllable/ˈwɪk·ɪd/. But I had better listen to native speakers and dictionaries.
wicked adjective (BAD) /ˈwɪk.ɪd/
Question: Do we have words that follow the same pattern when it comes to this exception?
