Cannot add link to profile editing page in functions.php

I am trying to add a link to my profile editing page by adding the following to my functions.php:

/**
 * Adds "Delete Account" option to the profile page.
 */
add_action( 'show_user_profile', 'modify_profiledelete' );
function modify_profiledelete( $show ) {

    ?>
	<h3>Account Deletion</h3>
    <tr id="password">
    <th>Delete your profile at the</th>
    <td><a href="http://www.removedforsecurity.com/delete-account">delete account page.</a></td>
    </tr>
    <?php

    return false;

it used to work on Twenty Twelve, but it just makes all of my website a blank page on Twenty Fourteen.
